摘要：<P>PROBLEM TO BE SOLVED: To provide an optical disk evaluating apparatus in which a test in the same position of an optical disk can be repeated with simple constitution by obtaining a position at which a signal is recorded and reproduced by arithmetic operation based on address information recorded in the optical disk. <P>SOLUTION: A head position on a track of the optical disk 10 corresponding to address information recorded in the optical disk 10 is calculated by a position arithmetic circuit 15, and the head position on the track of the optical disk 10 of a test signal to be accessed is calculated on the basis of the calculated position. <P>COPYRIGHT: (C)2006,JPO&NCIPI
