Disc apparatus

Abstract

A disc apparatus capable of automatic loading to load a disc and to unload a disc includes a plurality of arms for supporting outer peripheral edges of two kinds of discs with different diameters so that two discs can be transported, a loading slider, a clamping head moved up and down a plurality of times to clamp a disc by the loading slider when the loading slider is repeatedly moved forward and backward and a spindle motor for rotating the clamping head, wherein the spindle motor is driven by driving force previously set in response to the kind of the inserted disc at a proper time of the clamping operation period and which period is a period before and / or after the loading slider is operated in the reverse direction to thereby rotate the disc at a predetermined angle.

Description

technical field [0001] The present invention relates to an optical disc (such as CD-R / RW, DVD-R / -RW / RAM / +R / +RW, etc.) used to drive a recording medium for recording a large amount of information in various computer systems and other information equipment disk device. Background technique [0002] It is generally built into a disk device such as a personal computer (hereinafter referred to as a computer), and is usually equipped with a disk tray for loading disks, and the disk tray is configured by moving forward and backward. The disk loaded on the disk tray is driven in the disk device body to record or reproduce information. [0003] On the other hand, as a method not using a disk tray, a so-called slot-in type disk drive tends to be widely used, and is suitable for thinning and miniaturization of computers. Because of this slot-in disk device, the disk tray is not used when the disk is loaded (loaded) / unloaded (unloaded) from the device body. Once the operator inserts m...

Problems solved by technology

That is to say, even if only a part of the plurality of jaws cannot securely clamp the center hole of the disc, there is a possibility that information on the recording surface of the disc cannot be reproduced or recorded due to the tilted state of the disc and the inability to maintain a horizontal state.

Moreover, from such a state, if the disc falls off from the chuck, it will be out of the range of the loading device function, unable to be sent out, and the disc will remain inside the device, and there is a danger of damaging the recording surface of the disc.
