In 1993, Sony improved usability for everyday use. Recording and editing functions were introduced to support the transition from cassette tapes.
MZ-E2
The MZ-E2 is a MiniDisc player that incorporates early practical improvements to playback stability while maintaining miniaturization. It features a memory buffer that pre-loads and holds short audio clips, reducing skipping during transit and ensuring stable playback for portable use. While the casing is more compact than earlier models, it is still large compared to later players. Playback functions are limited to standard MiniDisc formats, and it supports track information display and operation via remote control. The power supply has been upgraded to a lithium-ion system, improving efficiency, but prolonged operation requires the use of an external power supply.
MZ-R2
The MZ-R2 is a second-generation model that maintains the basic performance of a MiniDisc recorder while achieving miniaturization and system simplification. Equipped with microphone input, line input, and optical input, it continues to ensure flexibility in terms of source material by supporting both analog and digital recording. Playback stability has been improved through buffer memory, and ATRAC processing has also been improved for greater efficiency. Recording levels can be set automatically or manually, but there are limitations to adjustments after recording has started. Editing functions have been streamlined compared to the first-generation model, and the configuration has been revised to focus on basic operations such as track marking and deletion.
In 1993, a structure suitable for playback and dubbing applications was established. At this stage, the expansion of the functional configuration was prioritized.
