Embodiment Construction

[0033] Preferred embodiments of an apparatus and method for controlling tracking error balance in an optical disc device according to the present invention will be described in detail with reference to the accompanying drawings.

[0034] According to one embodiment of the present invention, a disc or recording medium for recording includes a manufacturer identifier (MID) in a lead-in area. Information on write power suitable for each disc manufacturer is managed in the optical disc device. The MID is information that is unique to the disc manufacturer and can be used to identify the media or writing characteristics of the disc. If the MID is known, the appropriate write power for the disc can be known, and a power value corresponding to the degree to which data will not be recorded on the disc can also be calculated.

[0035] Therefore, in the present invention, in order to prevent data from being erroneously recorded on the disc in the process of controlling the tracking err...

Abstract

A method of controlling a tracking error balance in an optical disc apparatus, and the optical disc apparatus are discussed. In an embodiment of the present invention, when a tracking error balance for writing is controlled, a beam power that is appropriate for the writing characteristics of an optical disc is applied. The beam power can be determined based on the Manufacturer Identifier (MID) of the optical disc and writing power information for different MIDs. The beam power can be determined to be a value of 20 to 50% of the prestored writing power for the MID of the optical disc.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2006-118049 filed on November 28, 2006, which is hereby incorporated by reference as if set forth in its entirety herein. technical field [0002] The present invention relates to an apparatus and method for controlling tracking error balance in an optical disc device. Background technique [0003] Following the commercialization of the compact disc (CD), an optical recording medium capable of recording 74 minutes of music or about 650 megabytes of data, the digital versatile disc (DVD) capable of recording 2 hours of standard-definition (SD)-type movies It has been widely commercialized, and Blu-ray discs (BD) and high-density digital versatile discs (HD-DVD) capable of recording high-definition (HD) movies will appear on the market in the near future. [0004] Optical recording media such as CD, DVD, and BD are disk-shaped media that record data using optical characteristics, and data can be writ...
