Zusammenfassung:PURPOSE:To prevent a carriage from runaway when a servo-controlled LSI is a failure due to an overcurrent. CONSTITUTION:An overcurrent detecting circuit 13 is inserted between the servo-controlled LSI 4 and a power source. When the overcurrent is made to flow by the failure of the servo-controlled LSI 14, the overcurrent is detected by the overcurrent detecting circuit 13, then the rotation of a voice coil motor 8 is stopped by making the power supply stop to a voice coil motor driver 6. By this procedure, the carriage 9 is made to the standstill state, and the runaway of the carriage 9 is prevented.
