Embodiment Construction

[0024] Although the invention is described below for use with optical disc drives, it is also applicable to other types of drives with bays, for example for magnetic disc or tape drives.

[0025] Figure 1 shows an exploded view of an optical disc drive with a spring-actuated carriage movement mechanism according to the present invention. A disk module 9 for reading and / or writing from / to a disk (not shown) is mounted on the bracket 8 . Tray 13 receives a disc for playback or recording. On one side of the bracket there is a rack (not shown). A panel 14 (door) is attached to the front of the tray 13 and seals the tray opening in the disc player or recorder when the tray is in the playback or recording position. In order to fasten 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 comprises a main gear 2 driven by a torsion spring 6 mounted with a mounti...

Abstract

The present invention relates to a spring driven tray moving mechanism for a disk drive, such as an optical disk drive, and to a disk drive using such tray moving mechanism. According to the invention the mechanism includes: a spring for moving the tray (13), and a level adaptor (5) for lowering a disk module (9) during an initial phase, and for bringing the tray (13) into a position where the tray (13) interacts with the spring (6), the level adaptor being moved by the spring (6).

Description

technical field [0001] 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. Background technique [0002] Current disc drives with trays require electric motors to move the tray out of and back into 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 carriage. [0003] For example, US 5,699,338 discloses a disc drive with a tray actuated by a tensioned spring. To move the tray out of the player, the user pushes the door handle, thus releasing the spring. A spring then pulls the tray out through the player's opening. In order to slow down the movement of the carriage, the carriage is provided with a rack which interacts with a damping mechanism. To move the tray back into the player, the user pushes the tray through the opening, fully into the player, thus lo...
