Abstract:
1. An optical disk recording method of recording data in an optical disk by preparing, for each of a plurality of disk types, data of a waveform adjustment amount to be added to a record signal in accordance with the length of the record signal, the method comprising the steps of: (a) performing test recording for an optical disk whose data of the waveform adjustment amount is not prepared, by using the waveform adjustment amounts for all the disk types or a plurality of properly adopted disk types and by changing a record power; (b) reproducing test signals recorded by the test recording; (c) judging the qualities of the reproduced test signals; (d) selecting the waveform adjustment amount providing a relatively high signal quality; (e) adjusting the record signal by the selected adjustment amount; and (f) recording the adjusted record signal in the optical disk.
