Patent ID: 7023773

Claim:
A method of generating an optimum recording power for an optical recording medium in which land and groove signal tracks composed of a plurality of sectors are provided, data can be recorded in one of the signal tracks, and position information on the signal track where the data can be recorded is pre-pitted by a high frequency signal and recorded in the other signal track, and control information is wobbled in the signal tracks, the method comprising the steps of: synchronizing the sectors of a test area on the optical recording medium to perform an optimum power calibration (OPC), wherein the synchronizing step comprises detecting the signal wobbled on the signal track, PLL-locking the wobble signal, and outputting the PLL-locked wobble signal, and detecting a start position of the respective sector by counting the PLL-locked wobble signal; generating a recording pattern for performing the OPC; recording the recording pattern in a specified sector of the synchronized unrecorded test area as changing a recording power on the basis of a reference recording power recorded on the optical recording medium; reproducing the data recorded in the specified sector with the respective changed recording power, and determining the optimum recording power from the characteristic of a reproduced signal; and recording user data in a predetermined user data area of the optical recording medium with the determined optimum recording power.
