ABSTRACT:
An optical recording/reproducing apparatus includes an optical pickup unit configured to scan an optical disk with an optical signal to record and reproduce data. A power tuning unit is configured to scan a first track with the optical signal to record a first test data to the first track, while changing a power level of the optical signal within a predetermined range in sequence. A scanning time tuning unit is configured to scan a second track with an optical signal to record a second test data to the second track, while changing a scanning time within a predetermined range in sequence. A state detection unit is configured to detect a reproduction state of the first test data and second test data. A controller is configured to check the reproductions state of the first test data and second test data and determine an optimal power level and optimal scanning time. Accordingly, a write strategy is rapidly and optically tuned.
