Patent ID: 7349308

Claim:
A method of test recording to determine a recording power for recording information to an optical disk having a test recording area, the test recording area having a plurality of sections, the method comprising: using the sections of the test recording area consecutively from an inner periphery of the optical disk to an outer periphery of the optical disk for performing test recording when a read/write direction on the optical disk is from the outer periphery of the optical disk to the inner periphery of the optical disk, wherein the optical disk includes at least two recording layers each having the test recording area, said using of the sections of the test recording area consecutively from the inner periphery of the optical disk to the outer periphery of the optical disk for performing test recording when the read/write direction on the optical disk is from the outer periphery of the optical disk to the inner periphery of the optical disk is to carry out the test recording on a first recording layer of the at least two recording layers, and the method further comprises, for the test recording on a second recording layer of the at least two recording layers, using the sections of the test recording area of the second recording layer consecutively from the outer periphery of the optical disk to the inner periphery of the optical disk for performing test recording when a read/write direction on the optical disk is from the inner periphery of the optical disk to the outer periphery of the optical disk.
