Embodiment Construction

[0042] Reference numerals will be used in embodiments of the invention, examples of which are shown in the drawings, wherein like reference numerals refer to like elements throughout. In order to explain the present invention, embodiments of the present invention will be described below with reference to the drawings.

[0043] figure 1 is a block diagram of an optical recording and / or reproducing apparatus according to an embodiment of the present invention. refer to figure 1 , a pickup head and radio frequency (RF) detector 110 records data on or reproduces data from an optical recording medium such as an optical disc 100 . The pickup head and RF detector 110 includes a recording unit 111 and a reproducing unit 112 . The recording unit 111 shapes a laser beam emitted by a laser diode (not shown) into a write pulse on the optical disc 100 via an optical system (not shown). The reproduction unit 112 converts an optical signal reflected by the optical disc 100 into an electr...

Abstract

A method of optimizing recording conditions of an optical recording medium and an apparatus using the method. The method includes recording a test write pattern in a plurality of tracks of the optical recording medium; and checking a quality of a radio frequency signal reproduced from one of the plurality of tracks in which the predetermined write pattern is recorded and which is effected by writing in adjacent tracks to determine the optimized recording conditions.

Description

[0001] This application claims the priority of Korean Patent Application No. 2002-66574 filed at the Korean Intellectual Property Office on October 30, 2002, the disclosure of which is incorporated herein by reference in its entirety. technical field [0002] The present invention relates to the field of writing optimization for optical recording media, in particular to a method for automatically optimizing writing on optical recording media and an optical recording / reproducing device for executing the method. Background technique [0003] Various conventional methods for optimizing writing on optical recording media are known, which are applied to Digital Versatile Disc-Random Access Memory (DVD-RAM). However, these methods limit the structure of the optical disc to nucleation dominant technology. And writing optimization methods for rewritable optical discs using the fast growth method, such as compact rewritable discs (CD-RW), DVD-RW, etc., or next-generation high-density...
