1992 MZ-1
The MZ-1 was the first MiniDisc recorder to adopt random access discs instead of linear tape, significantly changing how recorded audio was handled.
1993
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.
The MZ-R2 was Sony's first major refinement of the MiniDisc recorder, replacing the bulky MZ-1 with a smaller body, revised internals, and a shape meant for true handheld use. Where the MZ-1 felt closer to a transportable deck, the R2 fit easily in a coat pocket and marked MiniDisc's move from early demonstration to practical portability.
The build remained solid, with a matte black finish, side-mounted controls, and battery options suited for mobile recording. A lithium-ion pack sat inside the body, while an external AA case extended runtime without adding much bulk.
Inside, the R2 introduced Sony's second-generation ATRAC codec, giving recordings a cleaner sound than the original. Optical and analog inputs supported dubbing or live recording, and basic editing covered track erasure, numbering, and navigation.
The R2 retained MiniDisc's ten-second buffer for skip resistance and shipped with a wired remote that reinforced its focus on portable use. MiniDisc became something you could rely on every day.
