I've been waiting for this.
I had an MZ-R55 in high school.  Pretty high end portable player, with record.  It was small, too.  I though MD was cool but i think one major flaw (as MP3 players were just starting up in 1998, and I had one of the first there, too) is that you had to play music into the machine in real time.  It did support S/PDIF input but it was real time.

This says the R55 used ATRAC 4.  Anyway, it sounded great even if it took a while for Sony to get there with audio compression.

				I forgot that MD was a magneto-optical format.  It uses a magnet to write, and the laser heats up the media to 200C which effectively erases the track before recording.  Playback is exclusively by laser, like a CD.  Pretty cool.

Wait, there was netMD.  It could transfer via USB, including track data.  Holy crap.  Had no idea they made this.  It was after I had mine.
In any even that is a perfect explanation for why MD didn't take off: everything it should have done came out too late to be relevant.

				Hi-MD??  1GB?  Man, minidisc really had a whole lifetime, outside of even my experience in the late 90s.
