Patent ID: 7006418

Claim:
An optical disk device for recording/reproducing data on/from an optical disk, the optical disk device comprising: a spindle driver IC internally including a monitor circuit for monitoring a junction temperature of a chip of the spindle driver IC and a comparison circuit for comparing an output of the monitor circuit with an arbitrary set temperature and outputting a temperature flag as a comparison result; a traverse driver IC; an actuator driver IC; and a CPU for controlling the operation of the optical disk device and monitoring the temperature flag outputted from the comparison circuit, the CPU performing a control so as to continue driving of the optical disk device when the junction temperature is lower than the arbitrary set temperature, and performing a control so as to suppress heat generation of the spindle driver IC when the junction temperature of the chip of the spindle driver IC is equal to or higher than the arbitrary set temperature by not having the spindle driver IC perform a forced acceleration or a forced deceleration of the optical disk for an arbitrary period of time.
