the D.A.S.C. switch set to ON, the
D.A.S.C. stores digital data corre¬
sponding to about 3 seconds of CD
playback in memory and reads this
data as it piays music. This guards
the listener from being troubled by
sound skip even in case signal read¬
ing error occurs.

During playback, the CD is
rotated at double the normal
speed and the sound data of
about 3 seconds beyond the
present playback position is
stored in memory.
When the readout from the
CD is interrupted due to a
vibration or shock, the sound
data read from the memory is
not interrupted.
The amount of stored data
recovers so that the circuit
can deal with the next possible
shock.
