     I think the bit error rate ( uncorrected ) for a clean Audio Compact Disc
is something like 10 e-04. Corrected, it is much higher. However, when they
get dirty, things rapidly deteriorate ( I heard a filthy one on a local station,
they, too skip just like regular records if fouled up enough ).;

     For people interested in the technical aspects of this, there is an
excellent treatise on the Compact Disc and its error correction schemes in
either April or May "Audio".

     The Audio Compact Disk has got to be at least 10,000,000 times better
than Shugart SA712 1/2 height floppies (thus far, I am 0 for 8 on these.
Now Vertex, on the other hand, I am 7 for 7.) { NOTE REPLACE FLOPPIES WITH
WINCHESTER ABOVE--ooops!) Anyone have any horror stories about SA712's
