< feature of MD-MT770 >

1. Minimum in the world size- ˜^(unknown word) is portable again by which one is achieved MD for MDLP.
Recording at time of the length of the MD stereo and reproduction circuit (MDLP) are built into. Because the stereo can be played, 320 minutes at most can be conveniently used for a lot of tune edits and preservations, etc. with the mini-disc of 80 minutes.
¦ The player who does not correspond to MDLP cannot reproduce the tune recorded in the LP mode.

< time which can be recorded to mini-disc for 80 minutes >
SP mode The stereo for 80 minutes.
Monaural length time mode It is monaural for 160 minutes.
LP2 mode The stereo for 160 minutes.
LP4 mode The stereo for 320 minutes.

In achieving arranging of a reduction in the adoptions such as picking up/super-thin mechanisms and small motors and the numbers of parts and main parts efficient and consolidating, the minimum of 78.9mm in width ~15.7mm in height ~71.9mm in the depth in the world. - The size/the thinness of one was achieved. The miniaturization of the volume about 16% and thin compared with present commodity (MD-MT77) about 7% was aimed at.

2. Portable MD is the first. - "Two-line display liquid crystal Nabis remote control" adoption which can be operated one all
It was assumed full remote control to be able to edit the recording operation and the character input, etc.A special key to call & decision of the menu can be adopted, and [it] operate it easily by the portable telephone sense. The display of the remote control liquid crystal assumed two-line display, and achieved the initial of each menu in the first line, and the selected content of the menu was achieved in the second line and an easy operation with the display and the union feeling was achieved.
*** Display of information of name of disk <adoption of liquid crystal of two-line display> (the first line), truck name (the second line), disk name (the first line), and time (the second line) simultaneously- Two is possible. Information on the mini-disc can be confirmed in one glance. *** <(> display of group name (the first line) and truck name (the second line) simultaneously when mini-disc to which group is set is used- Two is possible)
With the backing light, the display can be easily confirmed even by a dark point.

3. "MDLP group mode" adoption which is recorded and can reproduced according to group
When recording, the group of each album and each artist, etc. can be set in one mini-disc. Setting of the group is possible up to 99 groups or less. If the group is chosen and the tune which wants to be heard is selected, a target tune can be speedily reproduced. The feature of MDLP which four times or less a mini-disc can be collected for a long time can be enjoyed more conveniently.
In addition, various group edit functions that it was able to be had to use it conveniently were adopted.
1) "Group change" where tune can be moved to other groups
2) "Group top move" where group which specifies it can be moved to the first group of MD
3) "(*guruupuireis*)" by which tune in group can be collectively deleted
4) "Group booking" which can make group beforehand, and record to group later
5) "Group arrangement" which moves tune by which group is not set at the end of MD, and can hear it with same ‹Θ‡(unknown word) even in equipment not to be able to do group reproduction

4. "MDLP3 color Nabis" by which LED informs of shine use state
–{‘̏㕔‚ΜLED“_–ł̐F‚Ζ“_–Ε‰ρ”‚Ε˜^‰Ή₯ΔΆ’†‚Μ‹Θ‚ͺ‚Η‚Μ˜^‰Ήƒ‚[ƒh‚©ˆκ–Ϊ‚Ε; *** It is possible to confirm it (<tune of "Continuousness of blinking yellow/twice" and the LP4 mode> <"Orange/four time continuousness of blinking"> blink in the tune of "Continuousness of blinking green/once" and the LP2 mode in the tune recorded in the SP/monaural length time mode).; Moreover, three colors LED blink by various patterns according to the charge and the content of the operation, and the operation situation is produced fashionable.

5. *** It is easily <only putting> attached <the charge stand which can be charged>.
*** It is easily attached <the charge stand which can be charged> only by putting the main body in the portable telephone sense.
The accumulation of "Effect of the memory" generated on the nickel hydrogen charge pond is detected with the refreshing (electrical discharge) circuit built in the main body and the charge stand, and [it] refreshes it automatically (electrical discharge). The addition charge in the state of the capacity's of the battery remaining can be done at ease.

6. "Personal computer link function" of can USB connection
If optional "MD-personal computer connection kit (AD-PCR3)" is used, the personal computer which does not install the optical, digital output terminal can record the file of the music such as WAV in music CD set in CD-ROM drive and the personal computer and MP3 to MD digitally by way of USB.
The character input and the edit operation of MD can be easily done by the personal computer link on the personal computer.
[It] corresponded to "Library control" and "Label print".
c In "Library control", can [it] control on the personal computer, and character information be copied onto other MD by registering MD on hand. (The batch copy is possible character information in the disk)
c In "Label print", it is also possible to prepare 12 kinds of background patterns beforehand, and for the image data (Correspond to JPEG/BMP) of which the user took a picture with the digital camera etc. to label. Moreover, the print of the list of the name of a song in the disk etc. can be done, and how to enjoy MD extends further.

7. The recording for a long time and the reproduction are achieved.
Picking up super-thin efficient & equipped with the new hologram laser is adopted. LSI of ATRAC which can be called the heart of MD is 0 which uses the latest technology.; *** <˜^(unknown word)> ‘ζ(unknown word) <again> the 8.3th generation of low consumption electric power type of the MDLP mode compression extension correspondence LSI is adopted with 25ƒΚm process goods.; The decrease of the system consumption electric power by a high-speed rotation of the disk was achieved, picking up and the conserved electric power design of mechanism were aimed at, and the reproduction was achieved for the recording and a long time of a long time.
A continuous recording/about 49 hours can continuously be reproduced for a long time for long time of about 36.5 hours by using together about the nickel hydrogen charge pond and 1 high capacity alkali AA dry battery. Moreover, the reproduction of about 14 hours and recording/about 18.5 hours was achieved also on one charge pond. (Both at the LP4 mode)
The drive with the high capacity alkali AA dry battery of one (1.5V) can be achieved by the low voltage design, and the recording of about 19.5 hours/about 29 hours be reproduced. (At the LP4 mode)

8. Abundant reproduction functions such as convenient "Introduction reproduction" for the MDLP reproduction are installed.
The tune of the favor can be quickly retrieved from the disk recorded for a long time in the LP mode by "Introduction reproduction" function to reproduce each tune automatically by about five seconds. Additionally, a random reproduction, a random repetition, all tunes/variegated one reproduction function of the repetition reproduction etc. can be had to be enjoyed.

9. The digital recording level control is installed.
*** [It] tends <a digital radio, and LD etc. of each difference, BS voice broadcasting, and digital communication satellite broadcasting the recording level of CD> <smaller than CD the recording level>. The disk where the recording level becomes complete can be edited, and when reproducing, music can be enjoyed by the same volume if the recording level is adjusted when such a digital sound source is recorded.

10. High pitched sound quality design by which [it] sticks to quality of sound
The amplifier circuit adopts the +/- power supply audio circuit installed in the component etc.The high pitched sound quality can reproduce because there is no output capacitor which leads to the tone quality deterioration.
The high pitched sound quality in clearing with the expansion can be enjoyed by adopting 24 bit operation method and three dimension (axis direction/frequency axis direction/time direction of the amplitude) adjustment type (*bittoarokeishon'arugorizum*) in the part ATRAC where [it] compresses/the sound which becomes the nucleus of the tone quality of MD is extended.
It was possible to record from CD more faithfully, and AD/efficient 20 bit DA converter which achieved the recording/the reproduction of the high pitched sound quality was installed in the signal at a minute level.
X-BASS of a digital method can be adopted in the heavy bass reproduction, and a heavy bass with few noises with power be enjoyed.

11. Strength in vibration from the outside, and "‰Ή”ς‚Ρ(unknown word) guard memory" of about maximum 160 second (LP4 o'clock)
Music can be pleasantly enjoyed without doing sound ”ς‚Ρ for about the maximum 160 seconds at the LP4 mode even if intermitted vibration is received by installing of 16 Mbits DRAM.

12. The sampling rate converter of the personal computer which can record digital directly from running music information and BS/CS.
It is possible to edit it directly from the CS tuner and the BS tuner (with optical, digital output terminal) by digital(Optical optional digital cable AD-M1DC is necessary)

13. [It] corresponds to the business youth of the recording of the conference and the lecture etc.
"Microphone synchronized function" The recording starts automatically reacting on the sound and the voice. Moreover, the disk can be used without uselessness because a no sound of three seconds or more is perceived and [it] stops temporarily.
"Twice recording function of the monaural length time" It is possible to record by the twice at the disk display time in the monaural mode.
*** Because "<fast> function of twice of <‘•·(unknown word)> reproduction" the disk recorded in the twice recording mode of the monaural length time can be heard by usual twice the speed, it is very convenient to confirm the content of the minutes of the conference.
"Auto mark function of time" The point when the head putting out point can be automatically recorded at constant intervals (3/10 step of three minute/five minute/change), and [it] asks it again later is easily searchable.

14. "Character stamp function" from MD to MD by which character information can be easily edited.
After [it] records, the stamp of the sound of character information on mastering MD can be wholly done from MD to MD when editing it.

15. The (*wantatchiijekt*) mechanism with an easy disk change is installed.
Because the lid opens and the disk comes out automatically if the opening button is done in the slide, the disk change can be smoothly done.

16. Recording of CD sound synchronized of digital/analog correspondence
