Patent ID: 7106673

Claim:
An optical disk recording apparatus for recording desired data in an optical disk and reproducing the recorded data from the optical disk having an embossed part in which data exclusively used for reproducing are beforehand formed, a test area capable of recording a test data, and a recording area for recording desired data, said optical disk recording apparatus comprising: means for reproducing said data in said embossed part with a predetermined reproducing power and for determining a target evaluation index for the optical disk by calculating an evaluation index based on the RF signal reproduced from said embossed part of the optical disk; means for recording said test data in said test area by varying the recording power and for reproducing said test data thus recorded with said predetermined reproducing power to calculate a test evaluation index from the RF signal thus obtained for each of the varied recording powers; means for storing said target evaluation index, the respective recording powers employed, and the test evaluation indexes corresponding thereto; means for determining as an optimum recording power the recording power at which said target evaluation index stored in said storage means may be obtained, based on the relationship of the test evaluation index and the respective recording power, said relationship being also stored in said storage means; and means for recording the desired data onto said optical disk at the determined optimum recording power.
