Abstract
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.

A recording apparatus for an erasable optical disk, comprising:
- 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 corresponding write power levels,
- wherein the recording apparatus records data on the optical disk with the optimum write power level.
A method of recording data on an erasable optical disk, comprising the steps of:
- (a) determining 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;
- (b) obtaining a target modulation degree from the maximum of the modulation degrees;
- (c) determining an optimum write power level corresponding to the target modulation degree based on a relation between the modulation degrees and the corresponding write power levels;
- and
- (d) recording the data on the optical disk with the optimum write power level.
