Title: Recoding power control method of disk
Inventor: LEE WAN SOO
IPC: G11B7/004
Filed: 2005-04-20
Abstract: A method for controlling the recording power of a disc is provided to compensate a beta by an inferior condition in a high X-speed rating drive. If a disc is led in(S11), a pickup system acquires information of the led-in disc(S12). The pickup system performs OPC(Optimum Power Control) in a PCA(Power Calibration Area) in the inner circumference of the disc by using the acquired information(S13). The pickup system performs recording in an outermost circumference area with initial recording power by referring to the performed OPC data(S14). The pickup system measures a beta level while reproducing the outermost circumference area by the recording power(S15). The pickup system raises or reduces the recording power in a direction in which the measured beta level is identical to a target level, and searches optimum recording power(S16-S19).
