摘要：
A motor rotation control device for an optical disk player including a motor outputting rotation signals, a sensor for sensing the rotational direction and rotational state of the motor in response to rotation signals of the motor, a motor control signal generator for generating a motor control signal according to the rotational direction and rotational state of the motor, and a motor rotation controller for controlling the rotation of the motor in response to the motor control signal. The motor rotation control device operates independently of a system controller, thereby reducing the load on the system controller.
