To control the load and eject operations, the clamp switch located in the mechanism unit and the three detecting

switches located in the control unit are used. Depending on the combination of these switches' ON/OFF status, the

DSCSNS voltage changes.

The microcomputer can detect the status (A to E) by observing the voltage at the A/D port. The disc size detection (8

or 12cm) is also performed through this status change. The DSCSNS status and the status change in the load and

eject modes are shown in the figures 1.4.3 and 1.4.4 respectively.
