Problems solved by technology

[0005] In the conventional rotary optical disk drive, since the optical disk mounting device is radially arranged on the basis of the center of the rotating wheel, it is difficult to place more optical disks. Not only that, but also because the overall size of the optical disk drive is too large, it is difficult to manage and carry the disk. disc drive
[0006] Also, when a user pulls out a cartridge from the main body to check each tray or replace an old one with a new one, not only the desired specific tray but also other trays are pulled out, so it is difficult for the user to use it

Abstract

A disk drive includes a main frame; a cartridge slidably installed in the main frame; a plurality of trays stacked in the cartridge and slidably installed therein; an elevation unit for controlling a height of a turn table; a tray selecting unit for locking each tray to a state that each tray can be loaded or unlocking a specific tray among a plurality of locked trays to draw it out of the main frame; a loading unit for loading the specific tray, among the plurality of trays locked by the tray selecting unit to reproduce / record a disk by means of an optical pick-up unit, onto the turn table; and a driving unit for driving the cartridge, the elevation unit, the tray selecting unit and the loading unit.

Description

technical field [0001] The present invention relates to an optical disc drive, and more particularly, to an optical disc drive capable of using a plurality of trays and allowing a user to place and extract a desired specific tray in a desired manner. Background technique [0002] In general, an optical disc drive is a device for reproducing information recorded in an optical disc such as a CD (Compact Disc) or a DVD (Digital Versatile Disc) or for recording information in an optical disc. In this optical disc drive, when a tray with an optical disc placed thereon is loaded into a drive, the drive unit rotates the optical disc, and when an optical pickup unit (optical pickup unit) moves radially, the data stored on the optical disc The information in it is reproduced or the information is recorded on the disc. [0003] figure 1 is a perspective view of a traditional rotary optical drive. [0004] see figure 1 , the conventional rotary optical disc drive 10 includes a body...
