METHOD FOR GENERATING AN OPTIMUM RECORDING POWER IN AN OPTICAL RECORDING/REPRODUCING SYSTEM, CONCERNED WITH MORE EXACTLY GENERATING THE OPTIMUM RECORDING POWER

摘要

PURPOSE: A method for generating an optimum recording power in an optical recording/reproducing system is provided to determine an obtained recording power as an optimum recording power, and to perform a substantial data recording process with the determined recording power. CONSTITUTION: A system changes a recording power based on a reference recording power recorded on an optical recording medium, tests/records a 14T mark-space and a 3T mark-space in an unrecorded test area of a PCA(Power Calibration Area) of the optical recording medium, and tests/records a 14T mark-space and a 4T mark-space(201,202). The system reproduces data recorded in a test area while changing the recording power, and obtains an asymmetry value for the 14T and the 3T and an asymmetry value for the 14T and the 4T in each recording power step(203). The system determines a recording power in which a difference between the asymmetry values is nearest to 0 as an optimum recording power(204). The system records user data inputted in a user data area of the optical recording medium with the determined optimum recording power(205).
