| 20090034383 | DISK-SHAPED RECORD MEDIUM AND PRODUCING METHOD FOR SAME, DISK RECORDING METHOD AND DEVICE, AND DISK PLAYBACK METHOD AND DEVICE - To record specific information to a disk-shaped record medium and reproduce the recorded specific information without any influence on the error correction capability. Copy protection information (CPID) having an error correction code appended thereto, shuffled and otherwise treated is sent as a CPID bit block to an EDC rewrite circuit ( | 02-05-2009 |
| 20090122691 | Locking Aid For High Density Bd-Rom Discs - The present invention relates to information carriers in general and high density discs such as Blu-ray discs in particular. According to the invention a system is provided comprising an information carrier (1) and an apparatus for accessing said information carrier The information carrier having recording unit blocks ( | 05-14-2009 |
| 20090213710 | REPRODUCING INFORMATION FROM ANINFORMATION CARRIER - The invention described is an apparatus for reproducing information from an information carrier ( | 08-27-2009 |
| 20100034058 | ADDRESSING DISC STORAGE SPACE USING HEAD POSITION - Current BD specification prescribes that in an ADIP an address is expressed with 21 bits, 19 to indicate the corresponding RUB number, and 2 to be set to 00, 01 and 10 consecutively in the 3 successive ADIP corresponding to one RUB, the smallest addressable portion of data on a disc. From this it derives that at most 32.2 GB of storage space can be addressed. Due to recent developments however, a storage capacity of 35 GB per layer could be achieved. According to the invention, one or more bits are added to the 21 bits currently allocated to express an address. This additional bits however are not stored in the ADIP but left implicit, exempting from a heavy deviation from the current BD encoding rules. The additional bits are reconstructed by an apparatus on the basis of the position on the information carrier where the corresponding RUB is present. | 02-11-2010 |
