Abstract:
An optical disk device comprising:a spindle motor for rotating a disk;an optical head for writing or retrieving data on the disk;a cooling fan for cooling the inside of the device;a motor for rotating the cooling fan;a controller for outputting an information signal to control rotating operations of the spindle motor and the motor of the cooling fan;a first driver for adjusting current supplied to the spindle motor by using the information signal from the controller so that the spindle motor has a rotational speed corresponding to the information signal; anda second driver for adjusting current supplied to the motor of the cooling fan by using the information signal from the controller so that the motor of the cooling fan has a rotational speed corresponding to the information signal, andwherein the rotational speed of the cooling fan rotates in proportion to the rotational speed of the spindle motor for rotating the disk.
