Method and apparatus for optimally recording information on an optical recording medium
When an optical disk is inserted, a writing power which is optimal for the optical disk is detected from recording and reproduction of test data and the value of the detected optimal writing power is recorded in a specific area of the optical disk. When recording data on the optical disk a next time, the recorded optimal writing power is used, therefore unnecessary repetition of the procedure for yielding an optimal writing power can be prevented. The method for recording information on an optical disk according to the present invention comprises the steps of (1) reading the reference writing power recorded on the optical disk, (2) recording test data on the optical disk by changing the writing power within a range with respect to the reference writing power, (3) reproducing the test data recorded on the recording medium and detecting an optimal writing power from a property of the reproduced signal, and (4) recording the information indicative of whether the steps (1) through (3) should be conducted in a predetermined area of the optical disk. The present invention eliminates unnecessary delays in data recording and reduces data playback errors caused by the use of an inappropriate writing power.
