ABSTRACT:
A write control method which varies a write power in response to a recording speed, a recording density, and a type of recording medium, and an optical disc recording apparatus suitable for the write control method. The write control method includes preparing a plurality of standard power values corresponding to recording speeds or recording densities for a plurality of record marks, selecting one of the plurality of standard power values with respect to a record mark to be recorded according to a recording speed or a recording density, and controlling write power of a laser beam according to the selected standard power value. The write control method and apparatus improve recording performance of an optical disc recording apparatus by differently setting write power values according to recording speeds, recording densities, and types of recording media.
