I would question your first point... ;)
Agree that write speed would be less than read speed; however if you
consider that a MD recorder can accept a streaming digital input of CD
quality audio (via the optical in), encode it with ATRAC, AND write it to
the disk, all in real-time - then i think you'll find the bandwidth of the
system quite sufficient for removable media purposes on a PC. Plus the
benefit of the disks not being as easily affected (as floppies) by magnetic
fields....it all adds up...
In any case it would be vastly better than floppy drive technology which
should have been obseleted years ago...
IMO anyways ;)

The write speed is probably the biggest problem (ie I would think the read
speed would be less of a factor) - there is a finite time taken to heat the
metallic substrate to it's Curie Point and also a finite time from that
point for the write magnetic head to align the substrate.
The factors governing the time taken for these events are probably related
to laser power output and disc groove/spot size. The groove and spot size
is fixed by the MD format and laser power output is probably limited by
cost and physical size in relation to fitting it in a portable recorder.
