MiniDisc (MD) was a magneto-optical disc format introduced by Sony in 1992 as an alternative to compact cassettes. Some key facts about MiniDisc:
- Stores up to 80 minutes of audio per 2.5 inch disc. Uses ATRAC data compression for smaller file sizes.
- Offered features like instant track skipping, shock resistance, titling capability.
- First MiniDisc player/recorder was released in late 1992 in Japan, followed by a worldwide launch in 1993.
- Adoption was initially slow outside of Japan, as it competed with the newly launched CD-R/CD-RW formats.
- Sony partnered with major record labels (including their own company Sony Music) to release music on MiniDisc and push the format.
- Despite marketing efforts, adoption was still relatively niche in the UK compared to Japan. The format eventually declined with the rise of MP3 players and streaming music.
- MiniDisc had a loyal user base and continued to be produced into the early 2010s, but never replaced cassettes or CDs as the mass market standard.
