DISK TRAY CONTROL DEVICE OF AN OPTICAL DISK DRIVE MOTOR, ESPECIALLY IN RELATION TO CONTROLLING A DISK TRAY IN A POSITION PARALLEL TO A ROTOR OF AN OPTICAL DISK DRIVE MOTOR

摘要

PURPOSE: A disk tray control device of an optical disk drive motor is provided to supply at least one control member between a rotor and a disk tray, so that the control member can maintain a parallel relation between the rotor and the disk tray by controlling a compressive force applied to one of the rotor and the disk tray, consequently a time for polishing can be remarkably reduced. CONSTITUTION: An axial tube(41) is formed on a circuit board(42). An optical disk drive motor includes a stator(40) mounted on the girth of the axial tube(41) and a rotor(30) mounted on the girth of the stator(40). The rotor(30) includes a shaft(20) rotatively supported within the axial tube(41), and a ring magnet(31) attached to the stator(40) to induce the stator(40). A disk tray(10) is mounted on the rotor(30), and includes a hole where the shaft(20) of the rotor(30) pierces through. A supporting unit(11) is mounted in an upper section of a disk tray(15), and is firmly coupled with an upper section of the shaft(20). An optical disk located on the disk tray(15) is supported in a certain position by the supporting unit(11).
