Patent number: 9449642Abstract: A record carrier has a servo track indicating an information track intended for recording information blocks. The servo track has a variation of a physical parameter, referred to as wobble. The wobble is modulated for encoding record carrier information, such as addresses. The servo track is subdivided in modulated parts in which the frequency and/or phase of the variation deviates from the wobble frequency, and non-modulated parts. The slope of the wobble is substantially continuous at transitions between the modulated and non-modulated parts by using wobbles starting at the maxima or minima of the wobble in a first part of the modulated parts.Type: GrantFiled: December 30, 2013Date of Patent: September 20, 2016Assignee: Koninklijke Philips N.V.Inventors: Cornelis Marinus Schep, Aalbert Stek, Sebastian Egner, Constant Paul Marie Jozef Baggen

Patent number: 9431048Abstract: An apparatus generates outgoing data to be provided on an optical disk in a burst cutting area. The burst cutting area further comprises markings which cause a marking frequency spectrum when reading out the burst cutting area. The apparatus comprises a channel coder which receives processed data and supplies the outgoing data having an outgoing data frequency spectrum with suppressed DC-content. The apparatus further comprises a data processing device which generates the processed data to obtain an outgoing frequency spectrum wherein a frequency component causing interference with a low frequent component of the markings is suppressed or not present.Type: GrantFiled: November 8, 2013Date of Patent: August 30, 2016Assignee: Koninklijke Philips N.V.Inventors: Maarten Kuijper, Bart Van Rompaey, Jacobus Petrus Josephus Heemskerk, Cornelis Marinus Schep, Josephus Arnoldus Henricus Maria Kahlman

Patent number: 7975206Abstract: An ECC block is constituted by RS(248,216,33). Of a data length of 216 bytes (symbols), only 16 bytes are allocated to BCA data and the remaining 200 bytes are used for fixed data having a predetermined value. Using the fixed data of 200 bytes and the BCA data of 16 bytes, parities of 32 bytes (symbols) are calculated. Only the BCA data of 16 bytes and the parities of the former 16 bytes of the 32-byte parities, that is, a total of 32 bytes only, are recorded in a burst cutting area of an optical disc. In decoding, error correction processing is carried out by using the fixed data of 200 bytes. The unrecorded parities of 16 bytes are processed as having been erased. Thus, the error correction capability in a burst cutting area of an optical disc can be improved.Type: GrantFiled: April 18, 2007Date of Patent: July 5, 2011Assignees: Sony Corporation, Panasonic Corporation, Koninklijke Philips Electronics, N.V.Inventors: Shoei Kobayashi, Susumu Senshu, Tamotsu Yamagami, Makoto Usui, Hideshi Ishihara, Mitsurou Moriya, Cornelis Marinus Schep, Jakob Gerrit Nijboer, Aalbert Stek

Patent number: 7861142Abstract: Four ECC blocks are recorded in a burst cutting area of an optical disc. Each ECC block is constituted by a BCA content code of 1 byte, content data length of 1 byte, and content data of 14 bytes. Of the BCA content data, the leading 6 bits are used for application ID and the remaining 2 bits are used for block number. Disc ID is stored in the content data. Since the four ECC blocks exist, the optical disc can be managed individually by four applications at the maximum. Thus it becomes possible to manage the same optical disc by a plurality of applications.Type: GrantFiled: April 24, 2007Date of Patent: December 28, 2010Assignees: Sony Corporation, Panasonic Corporation, Koninklijke Philips Electronics N.V.Inventors: Shoei Kobayashi, Susumu Senshu, Tamotsu Yamagami, Makoto Usui, Hideshi Ishihara, Mitsurou Moriya, Cornelis Marinus Schep, Jakob Gerrit Nijboer, Aalbert Stek

Patent number: 7656780Abstract: An optical disc medium 10 having a wobbled track groove 12 includes three wobble patterns including a flat wobble pattern, a positive pulse wobble pattern, and a negative pulse wobble pattern. In the flat wobble pattern, the amplitude of the wobble from the lengthwise direction of the track groove is zero such that the track groove is flat. In the positive pulse wobble pattern, the amplitude of the wobble from the lengthwise direction of the track groove is positive such that the track groove is wobbled in a first direction perpendicular to the lengthwise direction. Further, in the negative pulse wobble pattern, the amplitude of the wobble from the lengthwise direction of the track groove is negative such that the track groove is wobbled in a second direction opposite to the first direction. Then, three data values can be recorded using three distinctive wobble patterns.Type: GrantFiled: September 12, 2007Date of Patent: February 2, 2010Assignees: Koninklijke Philips Electronics N.V., Panasonic Corporation, Sony CorporationInventors: Jacobus Petrus Josephus Heemskerk, Cornelis Marinus Schep, Aalbert Stek, Hiromichi Ishibashi, Shigeru Furumiya, Shoei Kobayashi, Jun Nakano

Patent number: RE44088Abstract: A record carrier (1) has a servo track (4) indicating an information track (9) intended for recording information blocks. The servo track (4) has a periodic variation of a physical parameter at a predetermined frequency, usually called wobble. The servo track has modulated parts for encoding position information according to a predetermined type of modulation. The record carrier includes a management area in which the servo track includes permanent data. The permanent data is encoded using a different type of modulation, but using the variations of the same physical parameter. Direct digital modulation (41) is proposed for the different type of modulation.Type: GrantFiled: June 20, 2012Date of Patent: March 19, 2013Assignee: Koninklijke Philips Electronics N.V.Inventors: Cornelis Marinus Schep, Aalbert Stek, Jacques Heemskerk
