Embodiment Construction

[0036] Reference will now be made in detail to the detailed description of the invention and examples illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. Hereinafter, the present invention will be explained by describing specific embodiments with reference to the figures.

[0037] Figure 5is an exploded perspective view of an optical disc drive according to an embodiment of the present invention. The first frame 110, the second frame 120 facing the first frame 110, and the tray 130 are shown. The spindle motor 160 rotates the optical disc 200 , and the optical pickup 150 approaches the optical disc 200 and writes and / or reproduces information on the optical disc 200 . The loading motor 170 loads / unloads the tray 130 . The loading motor 170 turns the gear 171 . Reference numeral 300 is a clamping mechanism.

[0038] A loading motor 170 and a pinion 171 are installed in the first frame 110 . In addition, the cam mem...

Abstract

An optical disc drive includes a chucking mechanism facing a turntable, supporting a surface of an optical disc and being rotated. The clamping mechanism includes: a clamper that magnetically approaches the optical disc when the spindle motor approaches the optical disc so that the optical disc does not come off the mounting portion when the clamping is not completely performed; The spindle motor is used to isolate the gripper from the disc when it is isolated from the disc.

Description

technical field [0001] The present invention relates to an optical disc drive, and more particularly, to an optical disc drive capable of being installed horizontally and vertically. [0002] This application claims the benefit of Korean Patent Application No. 2003-46328 filed on July 9, 2003 and Korean Patent Application No. 2003-55212 filed on August 9, 2003 at the Korean Intellectual Property Office, which disclose The contents are incorporated herein by reference. Background technique [0003] An optical disc drive is generally a device that writes or reads information by emitting light onto an optical medium (hereinafter referred to as an optical disc) such as a compact disc (CD) or a digital versatile disc (DVD). [0004] figure 1 is a floor plan showing a conventional optical drive. figure 2 is along figure 1 The sectional view taken by the line I-I' in. [0005] refer to figure 1 and 2 , the tray 20 is slidably mounted on the frame 10 . The frame 10 includes...
