A laser power optimizing method for multi-pulse recording is described. Multi-pulse recording uses the recording pulse formed by bias part and comb part. To obtain best readout signal characteristics and reduce the time for optimizing, new mark pattem is recorded and then two parts of the recording pulse are individually adjusted by evaluating the detected signals during pre-write testing. At the optimized laser power by this method, a good qualitative eye-pattern was obtained. As a result, this new method proves to be suitable for the multi-pulse recording and adapted to various disks with different recording properties.
