Method of Recording Data on a Dual-Layer Optical Write-Once Disc

摘要

The present invention relates to a method of recording data on a dual-layer optical write-once disc (10), comprising the steps of:creating a first-layer video-data fragment (28) on a first layer (20) of the optical disc, the first-layer video-data fragment extending from a minimum first-layer video-data radius within a data zone of the disc to an outer radius within the data zone of the disc, the outer radius defining a layer boundary (38), creating a second-layer video-data fragment (40) on a second layer (22) of the optical disc, the second-layer video-data fragment extending from minimum second-layer video-data radius within the data zone of the disc to the layer boundary,writing video data (32) to the first-layer video-data fragment, starting from an inner radius of the disc up to a maximum first-layer video-data radius smaller than or equal to the layer boundary,writing video data to the second-layer video-data fragment, starting from the layer boundary, andif the maximum first-layer video-data radius is smaller than the layer boundary, writing a Buffer Cell (66) to the first-layer video-data fragment extending from the maximum first-layer video-data radius to the layer boundary.;The present invention further elates to a dual-layer optical disc and an apparatus for recording data on a dual-layer optical disc.
