Publication number: 20080098051Abstract: A recording system records blocks of information on a record carrier according to a file management system. Data space on a partly and fragmented recorded record carrier (60-68) is managed as follows. The information includes a first type of information, such as video, and a second type, such a general purpose data. The first type has extent allocation requirements that include requiring an extent to accommodate a multitude of information blocks in a consecutive range of addresses and the extent to have at least a predetermined extent size. Data space is managed by selecting at least one partly recorded data area (67,63,68) of at least the extent size which data area contains information blocks (63) at recorded addresses, and subsequently creating a free data area (74) on the record carrier by moving the information blocks from the recorded addresses in the partly recorded data area to different addresses (73) outside the free data area (74) and correspondingly adapting the file management data.Type: ApplicationFiled: July 19, 2005Publication date: April 24, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Johannis Friso Rendert Blacquiere, Pope Ijtsma, Christiaan Edzard Van Haersma Buma, Wiebe De Haan, Dirk Hamelinck, Wilhelmus Jacobus Van Gestel, Johannes Jan Mons, Menno Anne Treffers

Publication number: 20070168689Abstract: A device for recording records information in blocks having logical addresses at a physical address (52) in a track on a record carrier. The logical addresses are translated into the physical addresses in dependence of defect management information, such as remapping tables, maintained in defect management areas. For avoiding remapping of real time information, such as video, a series of blocks (42) having a continuous logical address range is recorded in a corresponding allocated physical address range. In the event of a defect interrupting the allocated physical address range local offset information is generated for adding an offset to a local range of physical addresses in said address translation for skipping (61) the defect. The blocks logically following the last block before the defect are written at physical addresses following the defect, and an end portion (62) that extends beyond the allocated physical address range due to the defect, is accommodated elsewhere.Type: ApplicationFiled: June 17, 2004Publication date: July 19, 2007Applicant: Koninklijke Philips Electronics N.V.Inventors: Johannis Blacquiere, Pope Ijtsma, Dirk Hamelinck
