Abstract
An information processing system has a scanning apparatus which includes a brake mechanism for braking a turntable, on which an optical disk is mounted when the motor for rotating the turntable is stopped. A lock mechanism for preventing the optical head from moving is also activated. The lock mechanism operates in interlock with the brake mechanism when the brake mechanism is activated. The brake and lock mechanism are driven by a common drive source.
