Abstract:
1. A method of optically recording information on an optical disc including first and second recording layers, the method comprising the steps of: performing a focus jump between the first and second recording layers; generating a test signal; detecting a first address for test recording in the first recording layer; optically recording the generated test signal on the first recording layer at a position corresponding to the detected first address to perform test recording with respect to the first recording layer; reproducing the recorded test signal from the first recording layer; evaluating the test signal reproduced from the first recording layer to obtain a first evaluation result; deciding an optimal recording power for recording with respect to the first recording layer on the basis of said obtained first evaluation result; detecting a second address for test recording in the second recording layer; optically recording the generated test signal on the second recording layer at a position corresponding to the detected second address to perform test recording with respect to the second recording layer; reproducing the recorded test signal from the second recording layer; evaluating the test signal reproduced from the second recording layer to obtain a second evaluation result; deciding an optimal recording power for recording with respect to the second recording layer on the basis of said obtained second evaluation result; optically recording information on the first recording layer; optically recording information on the second recording layer; and recording, on a management area of the first recording layer, not only information for identifying an apparatus which made the information recording but also information representative of a manufacturer name for said apparatus.
