Abstract
Recordable DVD+R and DVD+R/W optical discs with two (or more) information layers are developed to double the data storage capacity and video recording time. A method and device are proposed to make dual layer DVD disc recordings compliant with the dual layer DVD-ROM standard Recording the data in a DVD-ROM compliant way on the dual layer DVD+R or DVD+R/W disc is obtained by shifting the middle zone area towards the inner radius of a disc in such a way that the data zones of both layers are filled up with data.
Claims16
A method of recording information on a user recordable multi-layer record carrier having a plurality of information layers including at least a first information layer and a second information layer for storing information, the method comprising acts of:
- receiving data content to be recorded on the user recordable multi-layer record carrier;
- recording the data content on the user recordable multi-layer record carrier such that the data content is substantially evenly distributed between each of the plurality of information layers and recorded in compliance with a ROM (read only memory) record carrier standard, wherein portions of the data content are recorded in data areas of the first and second information layers such that the data areas are superjacent;
- and
- shifting middle zone areas of at least the first and second information layers towards an inner radius of the disc such that inner radius data areas of the first and second information layers are filled with a portion of the recorded data content if the user recordable multi-layer record carrier is recorded with less than a full capacity of the user recordable multi-layer record carrier.
A user recordable multi-layer record carrier, said record carrier comprising:
- a plurality of information layers including at least a first information layer and a second information layer for storing data content recorded on the user recordable multi-layer record carrier such that the data content is substantially evenly distributed between each of the plurality of information layers and recorded in compliance with a ROM (read only memory) record carrier standard,
- wherein portions of the data content are recorded in data areas of the first and second information layers such that the data areas are of substantially equal size and are superjacent and wherein middle zone areas of at least the first and second information layers are shifted towards an inner radius of the disc such that inner radius data areas of the first and second information layers are filled with a portion of the recorded data content if the user recordable multi-layer record carrier is recorded with less than a full capacity of the user recordable multi-layer record carrier.
A method of recording information on a user recordable multi-layer optical disc having a plurality of information layers, the method comprising acts of:
- receiving data content to be recorded on the user recordable multi-layer optical disk;
- and
- recording the data content in data areas of the plurality of information layers such that the data content is substantially evenly distributed between each of the plurality of information layers and recorded in compliance with a ROM (read only memory) record carrier standard,
- wherein recording includes an act of shifting middle zone areas of the plurality of information layers towards an inner radius of the disc if the user recordable multi-layer optical disk is recorded with less than a full capacity of the user recordable multi-layer optical disk such that the data area of the plurality of information layers are (i) substantially equal size, (ii) substantially filled with a portion of the recorded data content and are (iii) spatially aligned.
