Wow, prices are sure coming down on CD players, and someone
mentioned that there was one out that was only 2 inches high.
Do you think we will be seeing CD players for cars any time
soon?  After seeing the latest walkman, I'll believe that
anything can be done.

Although some car CD mockups have been
shown, none are presently available,
and probably won't be for awhile.  The
tracking tolerances required, combined
with the harsh environment encountered
in automobiles makes the problem *VERY*
difficult.

If you have a CD player, try thumping 
it: you can probably get it to mistrack
(YUCK)

Mitsubishi (I think) claims they will have an automobile
CD player in the Fall of '84.

Yes, CDs are  succeptable  to shock  (hitting  the front of my CD player
with my fist makes it skip).  However, my player seems to have very good
immunity to low frequency  vibrations.  For example, I can put the CD on
a wobbly table and shake the hell out it and it tracks just fine.

Therefore, with a proper mechanical suspension system to absorb the high
frequency vibrations it shouldn't be that difficult to make a CD work in
a car.

I thought that the whole reason for the CD being so small
and being different from the laser video disk was so that
a car-borne player could be made that would be the same
size as a "normal" car radio.
