Abstract
An optical disk drive includes, a main body, a tray driven by a loading motor transporting a disk in or out of the main body, and a base chassis on which an optical pickup emitting a beam onto a recording surface of the disk is mounted. A rotary chassis, installed to rotate with respect to the base chassis, has a turntable on which the disk is to be placed. Also, the optical disk drive includes a skew adjustment mechanism controlling skew between the disk placed on the turntable and the optical pickup mounted on the base chassis by rotating the rotary chassis. The optical disk drive dynamically controls skew between the disk and the optical pickup so that light is incident on the disk in a precise direction, thereby increasing its performance of data recording and reproducing.
Claims13
An optical disk, drive comprising:
- a main body;
- a tray driven by a loading motor to transport a disk in or out of the main body;
- a base chassis on which an optical pickup emitting a beam onto a recording surface of the disk is mounted;
- a rotary chassis rotatably installed at an end of the base chassis, the rotary chassis having a turntable on which the disk is placed;
- and
- a skew adjustment mechanism to control skew between the disk placed on the turntable and the optical pickup mounted on the base chassis by rotating, and raising a free end of the rotary chassis, which is opposite the end of the base chassis.
A method of adjusting skew in an optical disk drive, comprising:
- transporting a disk in or out of a main body of the optical disk drive via a tray, the tray being driven by a loading motor;
- mounting an optical pickup on a base chassis to emit a beam onto a recording surface of the disk;
- mounting a rotary chassis to an end of the base chassis, the rotary chassis having a turntable on which the disk is to be placed;
- and
- controlling skew between the disk placed on the turntable and the optical pickup mounted on the base chassis by rotating, and raising a free end of the rotary chassis which is opposite the end of the base chassis.
