<P>PROBLEM TO BE SOLVED: To provide an optical disk recording/reproducing apparatus that communicates with an IC chip mounted on an optical disk without causing malfunction in reading and writing even if the optical disk is rotated. <P>SOLUTION: An antenna coil 14 of a reader or writer device that communicates with the IC chip in an optical disk is disposed at a side facing an optical pickup module 12 with respect to a rotation axis of the optical disk. Thus, effects of a magnetic field induced in the antenna coil 14 on the optical pickup module is decreased, so that even if the antenna coil communicates with the IC chip during recording/reproducing of the optical disk, malfunction does not occur. <P>COPYRIGHT: (C)2007,JPO&INPIT |
