Mini Disc
<storage, music> A music medium designed by Sony as a portable 
replacement for music Compact Discs. In 1994 Sony announced a data version which 
can hold 140 MB or about 100 MB using error correction. These will be 
competitive with 128 MB magneto-optical disks. Mini Discs may be either a 
re-writable or mass-produced read-only type. Sony have also announced a standard 
data format.
 
The transfer rate is similar to CD-ROM which is slow compared to the current 
magneto-optical drives (which are similar to an old hard disk, with writing 
noticeably slower than reading). Pre-recorded read-only Mini Discs can be mass 
manufactured on a modified CD press - this and the standard format mean it could 
take off as a software distribution medium.
 
An article in the December 1994 PCW quotes access times of about 300 ms and data 
transfer rate of about 150 kb/s (i.e. about single spin CD rate).
