BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disc apparatus, and more particularly, to a method for displaying optical disc information of an optical disc apparatus that can reduce recording failure when recording data on an optical disc.

In general, optical discs are discs for playback only, such as CD-ROM (CD-Read Only Memory), DVD-ROM, etc., CD-WORM (CD-Write Once Read Many), DVD-R, And write-once discs such as CD-RW (CD-Rewritable), DVD-RW, DVD-RAM (DVD-Random Access Memory), and the like.

In recent years, with the development of optical disc related technologies, optical disc devices capable of recording data on DVD R and DVD RWs have become widespread, and many disc manufacturers have developed DVD R and DVD RW media. Is released.

On the other hand, optical disc devices capable of recording data to DVD®R and DVD®RW support optical discs released by many manufacturers using built-in firmware, and users can upgrade to new media through firmware upgrades within the optical disc device. Can be used.

However, there are many optical disk manufacturers, but only a few manufacturers of optical disk devices are unable to develop firmware to support all media released by the media manufacturers.

For this reason, when an optical disc device records data on an optical disc produced by any manufacturer, it often fails to perform the recording properly if it does not support the optical disc. The hassle of having to compare media with spec information on disk units.

An object of the present invention is to solve such a problem of the prior art, and when the optical disk is loaded in the optical disk device, the MID information for the optical disk is extracted, and the corresponding MID information and the firmware information in the memory is compared through The present invention provides a method of displaying optical disk information of an optical disk device that can reduce an error caused by the optical disk while using the optical disk device by providing an OSD screen.

In order to achieve the above object, the present invention provides an optical disk information providing method loaded on an optical disk device for reproducing or recording data stored in an optical disk, comprising: a) any data recording for the data after the optical disk device is driven; Retrieving MID information recorded in the optical disc when the optical disc of the optical disc is loaded; b) comparing MID information for the optical disc with firmware data in the optical disc apparatus; and c) And displaying the presence or absence of support for the MID information and the arbitrary optical disk based on the comparison result.

Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing an optical disk apparatus for explaining a method of displaying optical disk information according to the present invention.

Referring to FIG. 1, an optical disk apparatus includes a disk loader unit 100, an amplifier unit 102, a flash ROM 104, an OSD unit 106, and a microcomputer 108.

The disc loader unit 100 is loaded with an optical disc, for example, an optical disc such as a DVD RW, DVD R, CD RW or CD-R, and records data input from the outside into the loaded optical disc or an optical disc. The data is read from the data and provided to the MPEG unit 102.

In addition, the disc loader unit 100 reads the MID information (optical disc information) recorded in the TOC area of the optical disc during the initialization process when the optical disc for recording, that is, the optical disc is loaded, before performing the recording operation. 108).

Here, the initialization process may include software and hardware initialization, chipset initialization, servo initialization, optical disk information reading and storage, and diagnostics.

The MPEG unit 102 performs MPEG signal processing on data input from the outside to provide the disk loader unit 100 or performs MPEG signal processing on the data output from the disk loader unit 100 to display on the display device.

The flash ROM 104 stores firmware data necessary for driving the optical disk device, and drives the optical disk device using firmware data when the optical disk device is initially driven. Such firmware data stores MID information of an optical disk supported by the optical disk device.

The firmware data stored in the flash ROM 104 may be updated by loading the optical disk storing the new version of the firmware data into the disk loader unit 100.

The OSD unit 106 receives predetermined data under the control of the microcomputer 108 to construct an OSD screen and display the OSD screen on the display device.

The microcomputer 108 controls the overall functions of the optical disk device, and in particular, compares the MID information of the optical disk provided by the disk loader unit 100 with information in the firmware data, and the MID information of the optical disk exists in the firmware data as a result of the comparison. In this case, the OSD unit 106 is controlled to display a message such as "It is a recordable disk" and MID information of the optical disk as an OSD screen and display it on the display device.

In addition, when the MID information of the optical disk does not exist in the firmware data, the microcomputer 108 controls the OSD unit 106 to configure a message such as "This disk is not supported" and the MID information of the optical disk as an OSD screen. Display on the display device.

The microcomputer 108 controls the OSD unit 106 to include the message and the MID information of the optical disk as well as the version information of the firmware data stored in the flash ROM 104 on the OSD screen.
