Patent ID: 7095691

Claim:
A data-recordable optical disk device, comprising: test data recording means for recording test data in a predetermined area of an optical disk while varying recording power level; test data reproducing means for reproducing said test data, recording power level setting means for setting an optimum recording power level based on reproduced signal quality of said test data; data recording means for recording data based on said optimum recording power level; and strategy setting means for setting a recording strategy for said test data and said data; wherein when said optimum recording power level determined based on recording of said test data using a first recording strategy does not exceed an allowable recording power level, said strategy setting means sets said first recording strategy as a recording strategy for said data, and, when said optimum recording power level exceeds said allowable recording power level, said strategy setting means sets a second recording strategy as a recording strategy for said test data and said data, said second recording strategy having an optimum recording power level no higher than said allowable recording power level, and said second recording strategy requiring less recording power compared to said first recording strategy.
