Special technologies defeated: MiniDisc
Sony recovery in our special technologies defeated and we are going to the field of audio, with the MiniDisc, a format that even today has enough followers, but which was never succeed in bulk.
As the Digital Compact Cassette, was an attempt to replace cassette tapes to digital format. Sony announced this in 1991 and went on sale in early 1992.
The MiniDisc is a form similar to that of a floppy with a size of 6.8 x 7.2 x 0.5 inches, with an outer casing which serves as protection with a sliding door and stored on the disc inside. It uses magneto-optical technology to store data.
The material is heated by a laser so that it becomes programmable via a magnetic field, which alters the polarity to record data. This allows rewritable discs up to a million times. To read only the laser is used.
