Abstract
A recording medium driving apparatus is provided. A signal from the tray position sensoris provided to the connection point E to control a mute signal generatorin 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 sensor, even though the HIGH signal is output on the buses. The mute signal from the mute signal generatoris output, and the sled motor driver, the spindle motor driver and the solenoid driver for driving the solenoidof 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.
