I seem to remember that the laser, when it goes bad, just stops
working.  There is no wearing out of it.  It works at 100%, one minute,
then not at all the next.  This is as opposed to a stylus which wears
out over time.  To me, the laser is better.  True, you are stuck without
a CD player for awhile, but I'll just use my PCM processor until it's
fixed.  By that time, the DAT (Digital Audio Tape) should be in mass
circulation.  Reports I have heard place it in availability in mid-1986.
