Abstract
A method for setting laser power of an optical disc device is provided. It is determined whether or not power curve data is present in a memory. If no power curve data is present, laser power self-setting is performed, and detected power curve data is stored in the memory, and then the laser power is set using the stored power curve data. Even if no power curve data is present in the memory for a variety of reasons, it is possible to easily set an optimal laser power suitable for the characteristics of the optical disc device set, thereby securing a stable playback operation and guaranteeing high recording quality.
