Patent number: 8477578Abstract: The present invention relates to a recording apparatus, record carrier and method of recording data on at least two layers of a recording medium by using a radiation power, wherein individual recording speeds are determined for respective ones of the at least two layers at different values of the radiation power. A recording speed to be used for recording on an individual one of the at least two recording layers is selected based on a maximum radiation power specified for the recording operation, and the speed of the recording operation is controlled individually for each of the at least two layers based on the selected recording speed. The determination of the individual recording speeds at different radiation power values may be written or embossed on the record carrier. Furthermore, a recording sequence used for recording on the recording layers can be set based on the sensitivities and thus recording speeds. Thereby, total recording time can be minimized for multi-layer recording media.Type: GrantFiled: January 31, 2011Date of Patent: July 2, 2013Assignee: Koninklijke Philips Electronics N.V.Inventors: Ronald Van Den Oetelaar, Hubert Cecile Francois Martens, Wilhelmus Robert Koppers, Pierre Hermanus

Patent number: 8068400Abstract: 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.Type: GrantFiled: October 13, 2009Date of Patent: November 29, 2011Assignee: Koninklijke Philips Electronics N.V.Inventors: Wilhelmus Robert Koppers, Hubert Cecile Francois Martens, Pierre Hermanus Woerlee, Johannes Leopoldus Bakx

Patent number: 7480225Abstract: This invention relates to a method for recording information on a multi layer record carrier. The information is recorded on the record carrier according to special filling patterns, such that the record carrier is compatible with the DVD-ROM standard while the time required for closing a session and/or finalizing the disc is reduced. The information is substantially evenly distributed over the layers in blocks of a predefined amount of storage space. The size of these blocks may be flexible and set by the method or read from the record carrier.Type: GrantFiled: August 20, 2004Date of Patent: January 20, 2009Assignee: Koninklijke Philips Electronics N.V.Inventors: Pierre Hermanus Woerlee, Hubert Cecile Francois Martens, Wilhelmus Robert Koppers, Robert Alberta Arnoldus Ponsen

Patent number: 7218603Abstract: A multi-stack optical data storage medium (20) for rewritable recording using a focused radiation beam (30), entering through an entrance face (25) is described. The medium (20) has a substrate (1a, 1b) and an L0 recording stack (2) and an L1 recording stack (3) both comprising a phase-change type L0 and L1 recording layer and the recording stacks are separated by a transparent spacer layer (4). The L0 recording stack (2) is present at a position closest to the entrance face (25) and has an optical transmission of TL0a and TL0c when the phase-change layer respectively is in the amorphous phase and in the crystalline phase. The medium (20) contains pre-recorded information modulated in at least one of: an embossed pregroove (21) in the substrate (1a, 1b), embossed pits in the substrate and recorded phase-change marks in at least one of the recording layers L0 and L1 (6, 11).Type: GrantFiled: May 14, 2003Date of Patent: May 15, 2007Assignee: Koninklijke Philips Electronics N.
