Embodiment Construction

[0051] FIG. 1 schematically shows an optical disc drive device 1 , suitable for storing information on or reading information from an optical disc 2 . The optical disc drive device 1 includes a device holder 3 . In order to rotate the optical disc 2 , the optical disc drive device 1 comprises a motor 4 fixed on a support 3 defining an axis of rotation 5 . To receive and hold an optical disc 2 , the optical disc drive device 1 comprises a turntable or clamping hub 6 , in this case a spindle motor 4 mounted on a spindle 7 of the motor 4 .

[0052] The disc drive device 1 also comprises a movable carriage 10 which is movably guided in the radial direction of the disc 2, ie substantially perpendicular to the rotation axis 5, by guide means (not shown for clarity). 16 shows the mechanical end stop of the carriage 10 relative to the equipment holder 3 . 11 shows a radial carriage actuator designed to adjust the radial position of the carriage 10 relative to the equipment holder 3 ...

Abstract

A disc drive apparatus (1) comprises a sledge (10) radially displaceable with respect to an apparatus frame (3); a platform (20) radially displaceable with respect to said sledge (10); a controllable sledge actuator (11) for moving the sledge (10) radially with respect to said apparatus frame (3); a control unit (90) for controlling said sledge actuator (11); a sledge stop detection means capable of detecting that the moving sledge (10) comes to a standstill. Said sledge stop detection means comprises radial displacement detection means for detecting a radial displacement of said platform (20) with respect to said sledge (10). Said control unit (90) receives an input signal (SXD) from said sledge stop detection means and is responsive to said input signal to switch off said sledge actuator (11) when said input signal (SXD) indicates that said moving sledge (10) has come to a standstill.

Description

technical field [0001] In general, the present invention relates to a disc drive device for storing information on or reading information from a disc storage medium in which the disc is rotated and the write / read head is relative to the diameter of the rotating disc. to move. The invention particularly relates to optical or magneto-optical disk drives, although the invention is also applicable in the context of magnetic disk systems. Hereinafter, the present invention will be specifically described in the case of an optical disc drive device, but it should be understood that the present invention is not limited to the optical disc drive device. Background technique [0002] As is known, optical storage discs comprise at least one track of storage space (either in the form of a continuous spiral or in the form of a plurality of concentric circles) for storing information. The CD can be read-only, the information on it is recorded during the production process, and the user ...
