Since 1996 the domestic MD market has met a period of real growth, and is anticipated to reach 5 million units in 1997, with portables accounting for 50% of the market. In particular, for ``system stereos'' [bookshelf systems], those equipped with MD decks account for 65% of the units sold, and 80% of the revenue. This is expected to magnify the importance of carry along portables. (per Sony's survey)

The MZ-R50 now going on sale is equipped with a newly developed Lithium Ion rechargeable battery and a thinner optical block and deck mechanism, through which a thickness of 19.7mm and a weight of 190g has been achieved (at approximately 70% the volume of the previous ``MZ-R30'' model), allowing handy, on the go recording and playback enjoyment.

For use as one likes, the unit is equipped with a 16 megabit DRAM, providing approximately 40 seconds of shock guard memory (4 times the previous model), making it completely appropriate for outdoor use. Furthermore, by reducing power consumption to approximately 59% (recording) and 64% (playback) of the previous model, 12 hours recording and 22 hours playback is possible on the included LiIon cell together with 2 alkaline AA cells. In terms of operation, the vertical style jog dial allows MD editing and character input to be carried out easily.

The MZ-E35, in an ``MD Jacket'' form factor with improved portability, has been reduced 25% in thickness compared to the previous model (``MZ-E30''). The main body's upper surface is diecast magnesium, improving strength and giving a high quality feel. By equipping it with a 40 second shock guard memory, vibration resistance has been improved. And, as successor to the previous model's 1.5V drive, a design that further reduces power consumption has been developed, allowing 6 hours playback on the internal gum pack rechargeable, or 8 hours on a single AA cell, an improvement by a factor of approximately 1.5 over the previous design, making 16 hours of playback possible when both cells are used together. By equipping the operation panel with a ``hold shutter'', already well known on cassette walkmans, accidental operation while in a pocket or bag is prevented.

The MZ-E25 is a casual design MD walkman available in silver, as well as blue and orange color variations. Its 1.5V drive works with either a single AA drycell or gum pack rechargeable, and the battery compartment's design allows either type of battery to be used. This makes an external battery case unnecessary and increases convenience and portability.

The 3 units going on sale include a newly developed LCD ``Stick Controller'' type remote control. Using the ``Shuttle Dial'' on the upper part of the remote control, MD operations such as playback, track selection, pause, etc., can be conducted even with one hand. With its stick type slim design, it looks smart even attached to a breast pocket or bag.

``MZ-E35'' main characteristics

5. Convenient ``push type'' open button
With consideration given to ease of use, a push type open button has been placed on the front surface of the unit.

6. Main unit equipped with small type LCD
Not just on the remote, the main body is also equipped with a small type LCD, allowing operating mode, track number and battery level to be confirmed.

Characteristics common to all 3 units

1. Newly developed LCD ``Stick Controller'' type remote control included
By pinching and pushing the shuttle dial, the ``Stick Controller'' allows MD playback, pause, and track seek operations to be carried out. On the LCD, the operating mode, song name, disc name, etc., can be confirmed.
... With it's aligator clip it can be easily attached and removed.
The headphone connection part is equipped with a normal stereo mini-jack, allowing you to also [honorably] use HiFi audio headphones.
