Patent ID: 7693027

Claim:
An apparatus for controlling a recording signal and stabilizing the recording signal during an initial write operation, the apparatus comprising: a light generator generating light used to write information to an optical disk; a light amount compensator setting a voltage level of the recording signal as a second level when the write operation is performed or stopped; and a light amount controller supplying energy to the light generator based on the second level of the recording signal until the voltage level of the recording signal reaches a first level after a rewrite operation is started and controlling the light generated by the light generator to be constant after the voltage level of the recording signal reaches the first level, wherein the light amount compensator outputs a compensation signal and sets the voltage level of the compensation signal as the second level when the rewrite operation is started, and wherein the light amount controller controls the voltage level of the recording signal to reach the first level using the compensation signal output by the light amount compensator when the rewrite operation is started.
