Abstract

A memory chip mounted on an optical disk provided with a data recording region, a TOC (Table Of Content) recording region, a clamp region, and a center hole, includes an MID (Memory In Disk) chip on a portion of the optical disk for recording index data, and a plurality of input/output terminals which are in contact with the MID chip. The optical disk enables index data to be quickly and conveniently recorded and searched for in accordance with physical contact between input/output terminals provided in a recording/reading apparatus and the input/output terminals provided in the optical disk.

Claims

1. A recording medium having mounted thereon a memory device, the recording medium having a data recording region, a management information region, and a region on which data are not recorded, the memory device renewing recorded information automatically by an RF signal without physical contact when information recorded on said management information region is changed.

2. The recording medium of claim 1, wherein the memory device is a memory chip.

3. The recording medium of claim 1, wherein the memory device is provided at a portion of the region on which data are not recorded.

4. The recording medium of claim 1, wherein the information about the recording medium is index data.

5. The recording medium of claim 1, wherein the information about the recording medium is information for reproducing data stored on the recording medium.
