Method and apparatus for protecting inhalation type optical disk driver

Abstract

The invention provides a protection method for suction optical-disk drive and a device thereof. A first sense switch is applied to detecting the actuation of a disk ejecting unit; a second sense switch is applied to detecting the actuation of a disk accepting unit; and a third sense switch is applied to detecting the actuation of a locating rod. Firstly, a disk is inserted in the start state for detecting the action of the first sense switch, the second sense switch and the third sense switch; when all sense switches act, the drive unit is started so as to load the disk automatically; then the third sense switch is checked to confirm if the state thereof is changed; when the state of the third sense switch is changed, the condition that disk is drawn out is detected; and then the drive unit is reversed immediately so as to eject the disk, thereby protecting the optical-disk drive.

Description

technical field [0001] The present invention relates to a protection method and device for an optical disc drive, in particular to a protection method and device for a slot-in optical disc drive. In the process of loading a disc, when the disc is detected to be pulled out abnormally, the disc is automatically ejected to protect the disc driver. Background technique [0002] Generally, the way of inserting and withdrawing the disc of the optical disc drive is mainly divided into tray type (Tray Type) and slot-in type (Slot-in Type). The tray-type optical drive utilizes the placement slot of the tray to carry the optical disc and push it into or slide out of the optical disc drive, so that the optical disc can be positioned or ejected. The slot-in optical disk drive directly inserts the optical disk into the entrance of the optical disk drive, that is, the optical disk can be automatically sucked in and guided to the location or ejected by the advancing and retreating disk me...

Problems solved by technology

However, the release mechanism does not stop the motor from running. If the user pulls out the disc slowly, the fast-rising movement will still cause scratches or pressure damage to the disc.

In addition, the above-mentioned protection mechanism needs to be arranged on a narrow guide rod, which not only increases the difficulty of manufacturing and assembling the optical disc drive and the cost of parts, but also is not conducive to the miniaturization or thinning of the optical disc drive.

Therefore, existing slot-in optical disc drives still have some problems to be solved in the protection of abnormal operation.
