MiniDisc
Forgotten Technology · 1992
Published
Sony launched MiniDisc in November 1992 as a recordable digital alternative to the cassette. The small 64mm disc sat safely inside a plastic cartridge, could be rewritten and offered quick access to individual tracks. ATRAC compression, portable players and editing functions made it possible to record, rearrange and carry music in a distinctly physical format.
Why It Mattered
It kept the satisfying routine of handling and labelling a removable music format while removing much of the awkwardness of tape. MiniDisc occupied a fascinating middle ground between the cassette and the MP3 player, gaining longer recording modes and computer links as listening shifted towards files.
Disc and cartridge
- The disc measured 64mm and used rewritable magneto-optical recording.
- Sony's MiniDisc development work began in 1990.
- Its cartridge protected the recording surface from dust and scratches.
First recorder
- Sony's 1992 MZ-1 could record and play MiniDiscs and included a numeric keypad.
- The first MiniDisc equipment went on sale in November 1992.
- Shockproof memory reduced skipping during portable use.
Format extensions
- MDLP used ATRAC3 to provide up to 320 minutes of stereo recording on an 80-minute disc.
- Net MD added protected high-speed transfer from a computer over USB in 2001.
