What are MiniDiscs?

MiniDiscs were announced in 1991 by Sony as a disc based digital medium for recording and distributing consumer audio that is ``near CD'' in quality. In 1993 Sony announced MD Data, a version of the MiniDisc for storing computer data.

There are two physically distinct types of discs: Premastered MDs, similar to CDs in operation and manufacture, and Recordable MDs, which can be recorded on repeatedly and employ magneto-optical technology. The disc itself is enclosed in a small (7cm x 7cm), convenient, cartridge.

11/11:We've kept quiet too long -- Sony's Digital Rights Mania finally lands them in court: Slashdot reports that a class action suit against Sony in California alleges that Sony's copy-protected audio CDs violate several California statutes, including the "Consumer Legal Remedies Act" and the "Consumer Protection against Computer Spyware Act," which prohibits -- among other things -- software that takes control over the user's computer or misrepresents the user's ability or right to uninstall the program. Earlier, Mark Russinovich investigated Sony's self-installing CD protection software and found it to be akin to spyware, intentionally hiding itself and providing no means of removal. Sony later released an uninstaller, but Mark has has looked at it and finds "Without exaggeration I can say I've analyzed virulent forms of spyware/adware that provide more straightforward means of uninstall".

The unit can record to HD from a variety of sources, including CD (8x) and MD (realtime, analog). // Christopher Clark points out further NetJuke info at Engadget (in English). The write: ``Sony seems intent on trying our patience recently with gadgets that offer cool hardware but are hopelessly hamstrung by DRM and own-brand lockins. Latest of the bunch is the NAS-A1 NetJuke stereo it's launching as part of the Any Music joint venture ....
10/13:Several readers point out coverage of Sony's MZ-EH70 MZ-EH50 Hi-MD players (mech. trans). The ¥19,000 and ¥17,000 (resp.) units feature a maximum battery life (AA+NiMH) exceeding 80 hours and incorporate PCM and ATRAC/ATRAC3/ATRAC3plus codecs, but lack support for MP3 playback. Further coverage at AkihabaraNews and AVWatch (mech. trans). (Discuss...)
10/12:Sony announces the pro-use PCM-D1 solid-state recorder at AES. The handsome unit features built-in microphones, analog (!) meters, 4 hour battery life on 4AA cells and 96KHz/24bit recording to 4GB internal memory (with a memory stick slot as well). Available in December for $2000. (Courtesy Boris Bengin) // Also from AES, a respected journalist in the audio field reports: I was told [by Sony's pro-audio division] that new Hi-MD models are being developed and that Sony had no intention of killing the format. ... They kept assuring everyone that Hi-MD in the pro market will continue.
9/25:A CanadaEast News article reports on Sony's announced restructuring, stating "Sony also fell behind Apple Computer Inc.'s IPod in what should have been its forte - portable music players - clinging to CD and minidisc formats and its own proprietary but unpopular format for digital music files. The IPod models are a big hit in Japan, where Apple began its ITunes store in August to rave reviews."
9/23:Strap points out a C|NET article laying out the Tough choices ahead for Sony. From the article: Stephen Baker, an analyst at The NPD Group, suggested Sony should cut out some of the low-visibility categories, including non-MP3 portable music players, clock radios and car stereos. "These midtier categories, ones where Sony has a history and where they may have a large but not a dominant share, are the logical ones to cut." // Todd Snyder contributes detailed plans for adding optical output to an MDS-JE480 MD deck. Todd notes that the MDS-JE480 is still available from Crutchfield and is the only MD deck currently available on the US market. // Minidisc Access is selling new blue 1GB Hi-MD blanks for $6.50 each until Oct 1.
9/22:The Washington Post reports that Sony will cut 10,000 jobs in a restructuring operation to "catch up with rivals such as ... Apple Computer and its popular iPod player in the portable music industry". What's in store for Minidisc?
9/18:Mark Bausch points out an informative LA Times article covering Sony's attempts to get its electronics and entertainment divisions pulling in the same direction. From the article:
Through the late 1980s and 1990s, Sony's electronics and entertainment divisions coexisted in an uneasy peace. [...] The electronics units agreed to hobble new devices with technologies that limited copying and deterred piracy, but the entertainment divisions gave lukewarm support at best to the new formats Sony's engineers developed. The whole was clearly less than the sum of its parts.

8/12:Sony won't play on iTunes? Strap points out a Business week article mentioning that despite Sony's non-participation in iTunes Japan, some Sony artists have definately put their tracks there anyway. Strap's comments: The article is talking about how the iTunes launch in Japan is a raging success and how Sony musicians are trying to get their music onto iTunes even though Sony hasn't reached an agreement with Apple. It's certainly food for thought, all of us minidisc junkies have seen how Sony's recording business has influenced the way that they design their players/recorders. Now they don't want to feed the iPod monster because they want a bigger piece of the pie for their own personal audio solutions but they don't want to hurt their recording business by not letting their artists sell music on the hottest thing going either. A house divided against itself cannot stand and Sony, in spite of it's new management's declared policy of breaking down the barriers between divisions, is one divided house right now for sure. I hope that they sort it out. I wouldn't mind seeing them dump their music and movie studios and get back to doing what they used to do better than anyone, making the most innovative electronic equipment in the world. (Discuss...) // Kurisu points out several nice reviews from the forums: A black MZ-DH10P pictorial, an MZ-RH10 review and MZ-RH10 vs. MZ-NH900 pictorial, from Christian Klukas (WinNMD creator) review on a silver MZ-DH10P with supplemental pics, and a DH710 review + pictorial.

4/20:Peter Ravn spots a Japanese press release for the Sony CMT-AH10 Hi-MD bookshelf system (mech. trans). Due the end of May, the ¥53,000 unit offers high speed CD->MD dubbing (Hi-LP=8X, Hi-SP=6X, PCM=4X, std-MD=2X), USB uploading, and can be used as a PC data drive as well. Akin to last year's Hi-MD portables, the unit records in Hi-MD and std-MD modes (SP, LP2, LP4) but does not support MP3 directly. Further coverage at AV-Watch (Japan) including a larger photo.

4/13:Hi-MD Macintosh support? Several readers point out Japanese news of the Buffalo MD-HUSB portable downloader (further coverage at Gizmodo and AV-Watch (mech. trans.)). The unit is a near clone of the Sony MZ-NH600D except that it supports native MP3 playback (as do the 2005 Sony Hi-MD units) and uses the BeatJam software package for audio transfer -- a package that would appear to have a Macintosh incarnation.

4/6:Ishii has made a nice translation of the interview with Sony's MZ-DH10P developers. Did you know the camera was originally slated to be 3 megapixels, but was scaled back to reduce the unit's overall size? (Discuss...) // Minidisco is accepting 2005 Hi-MD pre-orders, for delivery in mid to late April. They've also updated their Minidisc comparison chart.
4/1:This year's April Fools Joke is that there isn't one. But since today's Hi-MD Minidisc portables with USB storage functions and native MP3 recording follow logically from MP3 ideas of past spoofs, perhaps Sony's 2005 Hi-MD units that have all the ingredients to be great MP3 players yet are still encumbered by a silly DRM scheme will qualify. // Ed Barlow points out signs of a possible truce between the Blu-Ray and HD DVD camps. The article discusses the impetus for settling this war before sales commence and mentions Minidisc as one of Sony's "technically-superior products that failed in the marketplace." // MDcenter.nl posts the first picture of the Sony MZ-RH10 with its Euro/NA remote (scroll to bottom of page).

3/14:Bryce Ly points out a New York Times article stating Samsung is now what Sony once was. Relevant quote: When Sony was caught flat-footed with a late introduction of an Internet version of its 25-year-old Walkman, its profits from world audio sales fell a cataclysmic 48 percent in the final quarter of last year. Once again, Sony had coasted on an old technology, while competitors invested in new ones.

Shades of Blade Runner: The shiny buttons in the 5.6megapixel photo reveal the photographer's apparatus. // Minidisc Canada has plenty of 2004 Hi-MD gear still in stock, including the Sony MZ-NH700 for US$209 w/shipping.

3/6:Big Shakeup at Sony: Various news sources report that CEO Nobuyuki Idei will likely be replaced by Howard Stringer. A Wall Street Journal piece adds this Minidisc related commentary: The Walkman group has suffered from a split between those who believe Sony should make its gadgets compatible with a wide range of popular services and technologies -- like the MP3 music-encoding system -- and those who push Sony's proprietary technology -- such as Minidiscs and the Atrac music-encoding system.

They do vow to finally "grow up" however. And MacWorld has the same story from a slightly different perspective. // For Dutch readers, MDcenter.nl is having a contest offering Sony MCMD-R1 Hi-MD cardreaders.

12/10:Marck finds a positive MZ-NH1 piece in Australian IT, stating that in terms of sound quality at least, Sony's Hi-MD portables are indeed iPod-killers. // And an AudioGoGo article asks does the iPod have a future? They write however "I have to smile when I see Sony mentioned as a possible usurper of the iPod. This is the company that has limited the power of the MiniDisc format to protect its music businesses. Sony designers serve too many masters to come up with a product so much greater than the iPod to change the cultural currents. And lets face it the "Walkman" brand is years stale, compared to the iPod."
12/9:Barlow finds an interesting Forbes piece on Sony's NW-HD1 "the digital audio player we all love to hate".

A new version of Sonic Stage (v2.3) ships with the units. Could an MP3 blessed Hi-MD unit be in the works? // The NW-HD3 (above) comes none too soon. As TrustedReviews NW-HD1 review points out, the earlier unit's inability to play MP3 files, coupled with Sonic Stage (download manager) buggyness conspire to create an unfriendly (and unSony-like) user experience.
11/13:Barlow finds articles in The Miami New Times and The Harvard Crimson about the band Animal Collective that mention their use of Minidisc for collecting field recordings.

8/9:Sony MZ-NH900 available in UK: AVLand posts zoomable MZ-NH900 snapshots but states "It isn't as solidly built as Sony's previous 9xx series machines. Its bottom half is plastic and the bulkiness makes it rather more like the 7xx series."
8/3:Hi-MD Blanks in stock at Crutchfield: Brian Rost told us (and we called and checked), Crutchfield has 13 Hi-MD blanks in stock for $7/each with a lifetime warranty. Minidiscs again rare and expensive -- just like the old days! // A Wall Street Journal review of the Sony NW-HD1 hard-disk player does not speak well of Sony's challenge to the iPod. Their verdict: While the new Sony is smaller than the iPod and has much better battery life, it is markedly inferior overall. It has a confusing, complex user interface that makes it hard to use; weak software for the PC; an oddball music format that makes loading it with songs tedious; and a companion music download service that offers less than Apple's. The iPod wins this round, and remains champion. A long Sony discussion thread on Slashdot mentions Minidisc and is similarly negative (sample post: "I think the MiniDisc format had great potential, but Sony's insistence on idiotic copyright meaures just make it way too inconvenient to gain wide acceptance. I use it mainly because (A) I already invested in it and (B) it's easy to cart around, but the format is so needlessly crippled as to be sad.")

The unit has a unique zero-g detector that retracts the heads during free-fall (will it play music in space?). If only it handled native MP3 playback. // Sergio de Pablos (of Quesabesde) points out two items from JVC: (1) The RC-G1MD MD/CD boombox (mech. trans) featuring 4X CD->MD recording and a fancy front panel illumination scheme and (2) The SP-A200 Pouch Speaker (mech. trans). It's designed to both carry an MD player and be connected to it as a speaker. // Nicolas Roughol has kindly scanned several French magazine Minidisc reviews from the late 90's.

7/20:One step forward one step back: Bangraman posts a comprehensive comparison of the Sony MZ-NH1 vs the iPod Mini. Though the review points up the pros and cons of both machines, it reveals a debilitating limitation of Sony's SonicStage based Hi-MD upload function: audio upload is only possible into DRM-locked files or ATRAC3 CDs!. Fortunately Sony has stated that a standalone Wave Converter application will be available in autumn that will allow Hi-MD mic and line input recordings to be uploaded and exported to open .wav files, as they promised. (Read further...) // Richard Prinsloo finds a good Sony manuals website stocked with a surprising collection of manuals (and from whence we found, e.g. the Sony MZ-R910 user manual). // Did you know Alpine has an iPod compatible car stereo due this fall?

7/5:The won't-be iPod killer: Mark Bausch points out Forbes coverage of Sony's NW-HD1, which they find underwhelming, stating (of its MP3 incompatability): "This is similar to other Sony players that use Sony-only technologies like the Minidisc and the Memory Stick. This strategy is, we think, doomed." Even Sony execs don't seem to know which end is up when it comes to portable audio gear. See further coverage at SFGate.com, Gizmodo, c|net and Engadget -- the user commentary is damning, nearly all agreeing that lack of MP3 playback is a fatal blunder. (Discuss...) // Hi-MD operation manuals appear: Duane Galensky and Jeff point out manuals for Sony's MZ-NH1, MZ-NH900, MZ-NHF800, MZ-NH700 and MZ-NH600D Hi-MD portables on Sony's documentation site.

5/29:It's finally in the open -- Sony itself says that executive paranoia over music piracy is hobbling innovation: Clay Schneider points out a revealing Bloomberg News article on Sony's missteps in the digital age that have cost them $100 billion in market value. Howard Stringer (head of Sony's US divisions) is quoted as saying "Executives were so concerned about music piracy that they couldn't agree with designers on the kind of player to create. We didn't get there, and by that time, Steve Jobs was there." (Discuss...) // With a dash of schizophrenia then? PC World has further coverage of Sony's HMP-A1, the 20GB hard-disk audio player announced this week that supports native-MP3 audio but neither Sony's Connect online music store nor the ATRAC3/plus audio format. This unit is not to be confused with the 20GB Sony VGF-AP1 hard-disk player introduced last week that does support ATRAC3/plus and Connect, but not MP3-audio playback. // A few pieces we missed: A Tech Japan article on Sony's MZ-NH1 & etc. product page (mech. trans.) points out that the MZ-NH1 and MZ-NH600D cradle is no longer slated to provide USB connectivity, and that the units will be available in additional colors.

Although the 77 cent tax on Minidiscs won't change, the board did add new levies on hard disk digital audio players and recorders -- those with capacities above 10GB will receive a C$25 levy. The Canadian music industry had requested a tax hike that would have subjected 20GB hard drive based players to a $125 tax! // Barlow finds an interesting SFGate article about a US college student taking a Minidisc recorder into Afghanistan. // UK readers can enter to win an MZ-N510 Minidisc recorder at Megastar. // Minidisc is being suggested as a holiday gift, from Anchorage to Oregon.

Steve Jess spots the Aaton Cantar-X (brochure), a rugged 6 track HDD field recorder with a firewire interface, digital and analog inputs (to 24bit/96khz), and a 15 hour battery life. Not cool enough?

Wherefore art thou Sony? // Did you know there is a Russian Minidisc FAQ translation? // The Minidisc Zone (fan page) is back in action, featuring pages on recent Sony portable recorders.
12/3:Prerecorded Minidiscs no longer being made! Rob points out information from n5MD (the music group that released albums only on Minidisc) stating that Sony DADC has told them they "don't make Minidisc anymore."

It is the first hard spec we have seen for its improvement over the Type-R chip. // TeamDigital.net has freshened up their shopping pages to show shipping rates and options. They are also offering the Sharp MD-DR420 for US$230 and the Sharp MD-MT200 for US$170.

11/10:Barlow notes a CP article reporting that a coalition of retailers and technology companies has made a submission to the Commons committee on Canadian heritage asserting that the levy on recordable storage media is unfair and obsolete. The Canadian model of taxing storage media to compensate for (and permit) free music downloading is one promising possibility for ending the Recording Industry's Copy-prohibition nonsense. It is interesting that the coalition (which includes Apple and Sony) states that the levy "is a disincentive to the music industry from adopting innovative technologies to protect and manage their content". Yes, that's precisely the point! // Speaking of copy protection: Mark Bausch finds a New York Times article (cached) stating that Sony is starting trials in Germany of CDs that prevent users from copying songs to file-sharing sites but allows them to make copies for personal use on Sony music players. It appears the CDs will include a second copy of each track in ATRAC3 format.

MiniDisc Technology

The creation of the MiniDisc system began in 1986 and required the refinement of several technologies (reflected in a host of patents). Sony discusses the technical challenges and how they were overcome in an IEEE technical report on the rewritable MiniDisc system.

A single MD holds the same amount of music as a CD (up to 80 minutes in "SP" recording mode) but does so in one fifth as many bits by using an audio compression method Sony calls ATRAC (Adaptive TRansform Acoustic Coding). ATRAC is a form of perceptual coding, a data reduction technique that attempts to encode only the information audible to the human perceptual system. Sony describes the details of their ATRAC system in an Audio Engineering Society technical report. A (translated) interview that appeared in MJ Audio Technology Magazine with the creators of Sony's top of the line MD-JA3ES deck also helps explain the MiniDisc signal compression technology. ATRAC is the basis of Sony's SDDS cinema digital audio system.

Perceptual coding, based upon the masking effect, is also the principle behind the MPEG, Dolby Labs AC-3, and Bell Labs PAC (Perceptual Audio Coding) compression algorithms.

minidisc laser diagram

Recordable MiniDiscs use a variation on conventional magneto- optical methods that Sony calls "Magnetic Field Modulation", in which data is recorded using a 4.5mW semiconductor laser together with a magnetic head. As the disc sweeps past the laser, a tiny area on the MD's magnetic recording layer is heated to its Curie temperature* while the field of the magnetic head in contact with the other side of the disc is switched back and forth to write a data pattern. When the area the head has magnetized moves away from the laser spot it cools below the Curie point to become cast in a string of N and S magnetized regions on the disc, spaced 60 millionths of a centimeter apart, and corresponding to the stream of bits being recorded.

Playback is accomplished using the same laser at about 1/10th power, and makes use of a phenomenon known as the Faraday effect in which a light beam's plane of polarization is rotated when it passes through a magnetic field. The readout laser beam is aimed at, and reflects from, the previously recorded magnetic regions; the optical pickup detects the polarization differences corresponding to beam reflection from N or S magnetized regions in order to reconstruct the recorded bit stream. (*The Curie temperature is the point at which a magnetic material loses coercivity, allowing it to be magnetized by a very weak field. For the MD recording layer [a compound of Terbium, Iron, and Cobalt], this temperature is 180°C).

MiniDisc manufacturing is an exacting process that involves the use of vacuum sputtering machines in a clean room environment. Interviews with Drs. Gassmann and Voser of Balzers Process Systems in Liechtenstein (which makes the Sprinter, Sprinter 750, and Multi Sprinter for MD manufacturing), and a page describing the BPS Sprinter machine give more details about the MD manufacturing process. Sony DADC's MiniDisc Handbook (in PDF format) gives a technical guide to pre-recorded MD production. Sony Disc Manufacturing's website has a good deal of technical information for artists producing MiniDiscs. The MiniDisc (and Compact Disc) substrate itself is made from a plastic called Makrolon, developed by Bayer in Germany. It is a surprisingly resilient material, try bending a CD sometime.

Sony describes the Magneto-Optical (MO) recording technology used for MDs in a technical paper on their HS MO system. Sony Singapore has some good diagrams explaining MD technology. Sony Japan also has some colorful, mildly technical MD coverage, as well as a simple MD technology animation for kids, in English. The 1394 (a.k.a Firwire) Trade Association documentation page contains information on the AV/C Disk Media Type Specification MD - audio (.PDF) with many technical details about the MD-clip format.

Why should I buy a MiniDisc recorder/player?

Why indeed? This is a deep and important question about the wisdom of participating in the consumerism of our modern age, and whether cultivating a life of voluntary simplicity would not ultimately bring greater happiness. However, if you are only asking whether you should not buy some other gadget instead, read on.

Sony intended the format as a replacement for the Compact Cassette. It provides a relatively low cost solution to making high quality recordings, and compared to Recordable CDs, it is smaller, cheaper, re-writable and allows non-linear editing. Compared to all forms of tape, it provides random access, meaning that you can quickly select songs with the touch of a button.

Although the format has been slow to catch on in the US, MiniDisc continues to thrive in Japan. Sales in the US were hurt by high prices and a format war with Philips Digital Compact Cassette (DCC). DCC has since been taken out of production (both Philips and Matsushita (DCC's Japanese backer) have now begun offering MD products). This fact, combined with the lower prices of current MD equipment, has helped MiniDisc begin catching on in Sony's US test markets.

The only drawbacks to MD are the fact that you cannot make a perfect digital copy of one (there is generational loss in every decompress/compress cycle) and the price of MD equipment (MD units costs at least US$200, though Sony's 1998 Bundle5 provides a home recorder and portable player for about $300). Blank prices have dropped 4 or 5 fold since the format's introduction and one can find 74' blanks in Japan for about $2 and in the US for $3 to $4. Blank prices are dropping in other countries too as MDs gain acceptance.

An unabashed Minidisc fan argues the MD case (vs. DAT). And it seems that people who actually sit down and spend a little time with MiniDisc, giving it an honest hearing with their own ears, become quite fond of the format.

Hey Sony!

Here are a few suggestions and ideas for Sony, and other MiniDisc manufacturers:

You can also give a piece of your mind with Sony's feedback page. (Probably a little more direct than putting suggestions here, eh?)

The Future (seen mid-1999)

(From before, days of future past)

Conclusion (Apology?)

While I have outlined many encroaching technologies that will eventually help supplant MD, please note that these are future technologies. They are only minimally viable today, for cost and infrastructure reasons. Given current consumer technology, MD is the recordable audio format ne plus ultra. And as long as there exists a desire to store audio on a versatile, permanent and portable carrier, MD will have a following.


Feedback

Please address comments, updates, corrections, etc. to the webmaster. Regarding questions about MiniDiscs, even though I maintain these pages I am not a guru (and like everyone else, I was once a rank beginner), so I would prefer that MD questions be posted to the Minidisc Community Forums or the MiniDisc Mailing List so that everyone benefits from the discussion. Bear in mind that if you do email me an MD question, I am likely to answer it with a cc: to the MD mailing list unless you specifically instruct me not to. I also kindly request that you read the FAQ before posting.

All our contact Email addresses have changed due to the torrent of spam/virus messages. Please prefix your email address for us with "md-", e.g. "md-webmaster". Use the main domain name (i.e. minidisc.org) after the '@' symbol.

I am always happy to receive reviews of MD units, especially for unusual or unpopular equipment. Before beginning an article however, please have a look at my guidelines for authors.


Acknowledgements

I wish to sincerely thank Sony for having the vision to pursue the development of the MiniDisc, despite the risks it may present to their music sales. They continue to see technological innovation as the best way to ensure profitability.

I must also thank The IEEE, The AES, Sony, John Watkinson and Focal Press, MJ Magazine, Audio Magazine and Stereo Magazine for the often extensive (nay complete) excerpts I have taken from some material. I have notified the respective copyright holders of my publication of their work.

I owe a debt of gratitude to these others who have helped make this page possible: Sumit Shah created the first edition of the MiniDisc Page on November 24, 1995. Jamshid Afshar subsequently maintained the US mirror until Sep. 96. Miska Sulander (sulander@cc.jyu.fi) maintains the at the University of Jyvaskyla. Rich Brennan (brennan@oohahh.merk.com) donated space at his company, ConnActivity Internet Services, for the US MiniDisc Page. Nick Perry (nick.perry@amulation.com) kindly provides space for the UK mirror site and maintains the MD mailing list as well as the MD-L archive on his site Amulation.com.

Great thanks are also due the members of the MiniDisc mailing list, the information in these pages is in large part the assembled wisdom and information that has scrolled through the digests over the years that I have been a member. I am more an editor than an expert, winnowing the MiniDisc information signal from the noise.

To those alert readers and net surfers among you who contacted me with tips, I am much obliged. I greatly appreciate receiving email notification of new products and web sites, and I particularly prize scans of magazine articles. Anything you can send me will help to make these Web pages more informative and useful. When in doubt, drop me a line of email to see if I've seen it. Thanks!

May this page be of help to you. -Eric Woudenberg
