Optical disk recording apparatus and method of recording data on optical disk

摘要

A recording apparatus for an erasable optical disk includes: a first determination part which determines a maximum of modulation degrees of signals reproduced from a test recording area of the optical disk, the signals being recorded in the test recording area with corresponding write power levels different from one another; and a second determination part which determines an optimum write power level corresponding to a target modulation degree obtained from the maximum of the modulation degrees based on a relation between the modulation degrees and the write power levels, wherein the recording apparatus records data on the optical disk with the optimum write power level.
