ABSTRACT:
A recording medium driving apparatus is provided. A signal from the tray position sensor13is provided to the connection point E to control a mute signal generator80ain the driver IC. When the system controller is abnormal, the potential of the connection point E is low according to the signal from the tray position sensor13, even though the HIGH signal is output on the buses172, 75. The mute signal from the mute signal generator80ais output, and the sled motor driver, the spindle motor driver and the solenoid driver for driving the solenoid28bof the lock mechanism are maintained at the off state. Even though the system controller is abnormal, the sled motor and the lock mechanism of the tray are maintained at the non-driven state.
