Title: Technique for controlling motion of disk tray and pickup

Abstract: A technique for controlling the motion of a disk tray in which the movement of a pickup and the loading/ejection of the disk tray is performed using a single motor. A disk tray position sensor includes at least one switch turned on or off according to the position of the disk tray and senses the position of the disk tray to output a logic value combination according to the position. A controller generates a motor control signal according to the logic value combination from the disk tray position sensor and an external input command. A motor moves a pickup or the disk tray according to the motor control signal. A combining unit selectively transmits motor power to the pickup or the disk tray according to the rotation direction and rotation amount of the motor.
