Abstract
The present invention balances functions of an optical recording medium conflicting format-wise, such as effective placement of recording capacity and emphasis on random access performance. An optical disk in an optical disk format for random access which records management information and an optical disk for sequential recording are both stored in an optical disk magazine for storing multiple slim optical disks in the same magazine case.
Claims13
An optical disk magazine comprising,
- an optical disk for recording management data with a recording/reproducing format suitable for random access, and
- another optical disk for recording substance data with another recording/reproducing format suitable for great data unit of the substance data.
An optical disk recording/reproducing system comprising,
- an optical disk for recording management data with a recording/reproducing format suitable for random access,
- another optical disk for recording substance data with another recording/reproducing format suitable for great data unit of the substance data,
- a management data recording/reproducing device for recording the management data onto the optical disk and reproducing the management data from the optical disk, and
- a substance data recording/reproducing device for recording the substance data onto the another optical disk and reproducing the substance data from the another optical disk in accordance with the management data.
An optical disk magazine usable in a reproducing device, comprising,
- a first optical disk for recording therein an information,
- a second optical disk for recording therein a management data for identifying the information on the first optical disk and indicating an address of the information on the first optical disk, the first and second optical disks being discrete with respect to each other, and
- a magazine case for containing therein the first and second optical disks stacked in a thickness direction of each of the first and second optical disks so that the first and second optical disks aligned in the thickness direction by the magazine case are capable of being mounted onto the reproducing device all at once and being taken out of the reproducing device all at once.
