It was an elegant design, intended to serve as a more compact and practical 'walkman' format than the 'CD Discman'.
And they learned from the mistakes of the CD, in so far as the main cause its replay problems was surface damage and contamination, so encasing the disc in a sealed cassette made it far more reliable and immune to 'rough' handling. And the user-recordable discs used a magneto-optical principle that makes them far more robust than CD-Rs.
Although I was never bothered by the compression used for MD I would gladly trade the 90 minutes run time for say 60mins (or less, got a SHED load of discs!) of linear .wav.
It would have been a lot less. Sony's ATRAC was a 5:1 data-reduction system.
Amusingly, After Sony had launched the MD with ATRAC, some legal representatives of Dolby Labs went knocking on Mr Sony's door with copies of Dolby AC3 (Dolby Digital) worldwide patents pointing out where Sony had accidentally and unknowingly infringed upon them... A settlement was eventually reached and I believe Sony pays royalties to Dolby on its ATRAC-based systems. :lol:
