Problems solved by technology

[0004] Using the existing method, although it is not too heavy to load the BD cartridge into the system, when inserting a relatively light bare disk into the system, the tray will be damaged due to excessive force. It is inserted into the system relatively too fast, so the impact on the system will become larger, which may also cause the bare disk to fall out of the center, resulting in clamp failure
[0005] In addition, when inserting a general bare disk, because unnecessary excessive force is applied to the loading device, it will cause excessive loss of system power

Embodiment Construction

[0040] Embodiments of the disc loading method and the disc discriminating device of the disc drive of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] figure 1 and figure 2 It is an exploded perspective view and a plan view of a BD drive to which the present invention is applied. As shown, the BD drive consists of:

[0042] An optical pickup 2, arranged on the device substrate 1, for reading / recording data from an optical disc;

[0043] The feed system 3 includes devices such as a shaft motor 11 installed to rotate the optical disc 9, and is used to read / record data from the optical disc;

[0044] The tray 8 is equipped with the optical disc 9 of the bare disc or the BD cartridge, and obtains the driving force to load the optical disc 9 into or out of the inside or outside of the drive system;

[0045] BD cartridge holder 7, used for firmly stabilizing the BD cartridge 10 on the tray 8;

[0046] The loading dev...

Abstract

The invention concerns CD load method and its CD distinguish device for CD driver, which comprises, bounce out disk; sense the CD inserted is empty disk or cartridge disk; compare CD sensing signal; if it is empty disk, use force Fb loaded CD to drive disk, push it in system and insert to rotating-disk of rotation shaft motor, then record or play data on CD, finally use force Fb loaded CD to bounce out it; if it is cartridge disk, execute similarly operation aforementioned with force Fc loaded cartridge disk. This invention can prevent the over impact when inserting empty disk and over loss of system electric quantity, realize thinlization for CD cabin; besides, support of fixed cartridge disk box also has the function as CD distinguish device.

Description

(1) Technical field [0001] The present invention relates to an optical disc loading method of an optical disc drive and an optical disc discriminating device thereof, in particular to a disc compartment mechanical device of a BD drive which is compatible with bare discs such as CD / DVD and a BD (blue disc) cassette disc. In the state of ejection, a disc loading method of a disc drive and a disc discrimination device thereof are capable of distinguishing a BD cartridge disc from a general bare disc. (2) Background technology [0002] In order to insert the disc into the internal system of the general BD drive disc compartment, after the tray is ejected, the disc such as a cartridge disc or a bare disc is installed on the tray, and the tray enters. Under the action of the loading device, it enters the interior of the system [0003] In the disc compartment of such a BD drive, because the disc type cannot be judged when the tray is ejected, a program with a constant force value...
