ABSTRACT:
A method and apparatus of controlling an optical disk apparatus determines a reference recording power at each of a plurality of recording speeds for an inserted optical disk, performs a power control procedure for a prescribed recording speed to determine a recording power at the prescribed recording speed in response to a recording request, and then computes a recording power at each of the recording speeds based on the reference recording power and the recording power determined at the prescribed recording speed. The power control procedure is performed only for an inner circumferential area of the disk, irrespective of whether a requested recording speed is less than or greater than the prescribed recording speed. As a result, the speed of the data recording operation may be substantially improved and/or other improvements may be realized.
