Abstract
An optical disc, and a recording/reproducing method and apparatus to record information on the optical disc. The optical disc includes an optical information storage layer, including a layer format region and a user data region. The layer format region is divided into virtual layers that are disposed at different depths. The virtual layers include layer information to distinguish the virtual layers from one another.
Claims16
An optical disc comprising an optical information storage layer comprising:
- virtual layers disposed at different depths in the information storage layer;
- a layer format region;
- and
- a user data region,
- wherein the virtual layers have layer information to distinguish the virtual layers from one another, recorded in the layer format region.
A recording/reproducing method for an optical disc comprising an optical information storage layer, the recording/reproducing method comprising:
- dividing the optical information storage layer into a layer format region and a user data region;
- dividing the layer format and user data regions into virtual layers that are each disposed at different depths in the optical information storage layer;
- and
- recording portion information in each of the virtual layers, in the layer format regions, to distinguish the virtual layers from one another.
A recording/reproducing apparatus for an optical disc comprising an optical information storage layer, the recording/reproducing apparatus comprising:
- a hologram recording/reproducing optical system to record information in the optical information storage layer and to reproduce the recorded information;
- and
- a control unit to divide the optical information storage layer into a layer format region and a user data region, to divide the layer format and user data regions into virtual layers that are each disposed at different depths in the optical information storage layer, and to control the optical system, such that the optical system records layer information to distinguish the virtual layers from one another, in each of the virtual layers, in the layer format region.
