Abstract: PURPOSE: An optical pickup device of an optical disk drive is provided to slightly raise a slider from a recording surface of a disk by an air bearing effect, thereby maintaining a near field between an objective lens and the disk. CONSTITUTION: An objective lens(21) focuses an incident light on a recording surface of an optical disk. A slider(23) is raised by an air bearing effect generated in a gap with the optical disk, and forms a near field in the gap with the optical disk. A flexure(25) supplies a degree of freedom capable of performing rolling and pitching movements in the slider, when the slider is raised from the disk. A coil bobbin(27) is composed of a winding part(27a) and four supporting bars(27b) extended from both ends of upper/lower sides of the winding part. An optical head(20) elastically moves in a focusing direction and a tracking direction by four wire suspensions(30). The wire suspensions whose both ends are fixed into a block body(10) are transformed in the focusing and the tracking directions by an external force, and move the optical head. A driving unit(40) supplies the external force.

Abstract: PURPOSE: A device for correcting the eccentricity of a disk for recording/playing back information and a method thereof are provided to correct the eccentricity of the disk at an assembling. CONSTITUTION: The recording/playback head(20), a rotary plate for encoder(50), an encoder(60), a discriminating unit and a pushing device(70) are prepared. The first eccentric amount is calculated from a maximum tracking error by rotating a disk(10). The discriminating unit searches rotary angles(theta1,theta2) of a disk when the maximum tracking error is detected. The disk is located at the angel(theta1). The disk is pushed as the first eccentric amount/2 toward a rotary shaft by the pushing device. A second eccentric amount is calculated by rotating the disk again. The disk is located at the angle(theta1) and pushed as the second eccentric amount when the first eccentric amount is larger than the second. Otherwise, the disk is located at the angle(theta2) and pushed as the second eccentric amount.
