Publication number: 20140022882Abstract: An optical disc (120) has a first mark (131) disposed at the center of a track, a second mark (132) disposed away from the center of the track in a tracking direction thereof by a distance b1, and disposed away from the first mark (131) in the direction along the track by a distance L, and a third mark (133) disposed away from the center of the track in the tracking direction opposite to that of the second mark (132) by a distance b2, and disposed away from the first mark (131) in the direction along the track by a distance L2. The second and third marks (132) and (133) generate scattered light depending on the distance between a scattering medium (103) and each of the marks by irradiating the scattering medium (103) in an optical information apparatus with light. The distances b1 and b2 are smaller than 50 nm.Type: ApplicationFiled: April 9, 2012Publication date: January 23, 2014Inventors: Kousei Sano, Tatsuya Takaoka, Hidenori Wada, Keiichi Matsuzaki

Patent number: 8634287Abstract: An information signal area on an information signal recording surface is provided as pits on a mirror in accordance with modulated information data, and is covered with a metal alloy reflective film. Sections that do not include pits corresponding to the information data are provided in the information signal area, and portions of the metal alloy reflective film on the sections are formed as perforated marks corresponding to the information data. In this case, the reproduction signal amplification level of a prepit signal and the reproduction signal amplitude level of a perforated mark signal can be obtained as substantially equal values by adjusting the depth and width of pits and/or adjusting the width and length of perforated marks. Hence, waveform distortion due to a waveform equalization circuit and variations in binary signals due to displacement of the slice level are reduced so that signals can be stably and reliably detected with the same reading apparatus.Type: GrantFiled: December 8, 2008Date of Patent: January 21, 2014Assignee: Sony CorporationInventors: Tetsuhiro Sakamoto, Jun Nakano, Takayuki Asahina, Etsuo Shibasaki, Hideo Kawachi

Publication number: 20140010057Abstract: A super-resolution optical recording medium (10) of the present invention includes: a medium information region (1) on which medium identification information is recorded; a content region (3) on which content information is recorded; and a blank region (2) provided between the medium information region (1) and the content region (3) and in which at least two tracks are provided so as to connect a train of prepits in the medium information region (1) and a train of prepits in the content region (3). No information is recorded on the blank region (2). With this arrangement, the present invention provides a super-resolution optical recording medium in which a region on which medium identification information is recorded and a region on which content information is recorded are different in track pitch and in which a reproduction error hardly occurs when reproduction shifts from the region on which the medium identification information is recorded to the region on which the content information is recorded.Type: ApplicationFiled: September 16, 2013Publication date: January 9, 2014Applicant: SHARP KABUSHIKI KAISHAInventors: Toshihiko Sakai, Hirohisa Yamada, Masaki Yamamoto, Yasuhiro Harada, Go Mori, Hideharu Tajima, Nobuyuki Takamori

Patent number: 8619530Abstract: Reading a partly written writable record carrier having a track structure for positioning the write head above unwritten areas of the track pattern by means of a reading device which positions the read head on the basis of written marks, yields problems when an isolated information block after an unwritten area must be read. A system is disclosed for writing and reading information blocks on a record carrier of a writable type such as a CD-RW or a DVD-RAM. The writing device is provided with status means for generating status information which is indicative of the fact that at least one area of the record carrier has been written, while the status information comprises initial-area information which is indicative of an uninterrupted written initial area which extends from the start of a track pattern area intended for writing information blocks. The status information can be fixed on the record carrier. A reading device is also described, in which the positioning is dependent on the status information.Type: GrantFiled: September 30, 2009Date of Patent: December 31, 2013Assignee: Koninklijke Philips N.V.Inventors: Gusbert J. Van Den Enden, Antonius P. G. E. Janssen, Arnoldus J. Niessen, Cornelis Teunissen, Franz H. U. Frank

Patent number: RE44678Abstract: An information system according to the invention comprises a record carrier and a playback apparatus. The record carrier has information marks along a track thereof and exhibits first variations caused by existence and nonexistence of the information marks along the track. The first variations represent an information signal recorded on said record carrier. The record carrier further exhibits second variations caused by variations associated with the information marks. The phase of the second variations is coupled to the phase of the first variations.Type: GrantFiled: June 13, 2008Date of Patent: December 31, 2013Assignee: Koninklijke Philips N.V.Inventors: Job Cornelis Oostveen, Willem Marie Julia Marcel Coene, Jan Harm Boer, Franciscus Lucas Antonius Johannes Kamperman, Aloysius Michael Josephus Maria Spruijt, Paulus Reinier Joannes Van Roosmalen
