Embodiment Construction

[0046] Although it is described in the following that the present invention is applied to an optical disk drive, it can also be applied to other types of drives with a tray, such as a magnetic disk or tape drive.

[0047] figure 1 An exploded view of an optical disc drive with a spring-driven carriage moving mechanism according to the present invention is shown. A disk module 9 for reading and / or writing from / to a disk (not shown) is mounted on the bracket 8. The tray 13 receives a disc for playback or recording. There is a rack (not shown) on one side of the bracket. The panel 14 (door) is connected to the front of the tray 13 to seal the tray opening in the disc player or recorder when the tray is in the playback or recording position. In order to secure the disc on the rotatable part of the disc module 9 during playback or recording, the bracket is further provided with a magnet holder 2. The carriage moving mechanism mainly includes a main gear 3 driven by a torsion spring 6...

Abstract

The present invention relates to a spring-driven carriage movement mechanism for a disk drive, such as an optical disk drive, and to a disk drive using such a carriage movement mechanism. According to the invention, the mechanism comprises: a spring for moving the carriage (13); and for lowering the disc module (9) at the initial stage and bringing the carriage (13) into the carriage (13) with the spring ( 6) The height adapter (5) at the position of interaction, which is moved by the spring (6).

Description

Technical field [0001] The present invention relates to a spring-driven carriage moving mechanism for a disc drive such as an optical disc drive, and to a disc drive using such a carriage moving mechanism. Background technique [0002] Current disc drives with trays require an electric motor to move the tray out of the player and to move the tray back to the player. In order to save the cost of the electric motor, it has been proposed to use a compression or tension spring to drive the bracket. [0003] For example, US5,699,338 discloses a disc drive with a bracket, which is driven by a stretched spring. To move the tray out of the player, the user pushes open the door handle, thus releasing the spring. Then, the spring passes through the opening of the player to pull the bracket out. In order to slow down the movement of the carriage, the carriage is provided with a rack, which interacts with the damping mechanism. To move the tray back to the player, the user pushes the tray th...
