Publication number: 20070159947Abstract: First identification data and second identification data are read out from a phase-change optical storage medium having a light-incident surface through which a light beam is to be incident and at least a first film-laminated layer structure and a second film-laminated layer structure provided over the surface in which the first structure is provided as closer to the surface than the second structure is. Each structure has at least a recording film. The data indicates first recording requirements to the first structure. The second data indicates second recording requirements to the second structure. The first and second requirements are different from each other. Given data to be recorded is modulated into modulated data. A data-recording signal having at least one mark followed by a space is generated based on the modulated data. The mark has a mark length nT (âTâ being a unit dock cycle, and ânâ being a positive integer of 3 or larger but 14 or smaller).Type: ApplicationFiled: January 8, 2007Publication date: July 12, 2007Applicant: Victor Company of Japan, Ltd. a corporation of JapanInventor: Ikuo Matsumoto

Publication number: 20070159948Abstract: The invention relates to a method of providing timing error information in optical systems, especially for reading high capacity optical discs, i.e. optical discs with a capacity of about 27 GB or above. At these capacities current threshold crossing timing recovery does not perform well and even becomes unfeasible due to severe inter-symbol interference. The method suggests using an upper and/or lower secondary eye in the eye diagram of the data signal to acquire the timing error information. Hereby, threshold crossing timing recovery becomes feasible for high capacity optical systems, where the central eye is closed or nearly closed due to the inter-symbol interference.Type: ApplicationFiled: February 1, 2005Publication date: July 12, 2007Applicant: KONINKLIJKE PHILIPS ELECTRONIC, N.V.Inventor: Bin Yin

Publication number: 20070159949Abstract: In one embodiment, the recording medium includes a user data area on which one or more recording ranges are allocated and a management area. The method of recording on the recording medium includes receiving an overwriting command to record data on a recorded area of a recording range. Each recording range is one of an open recording range having a recordable position and a closed recording range not having a recordable position. An open recording range is selected fro recording the data from the one or more open recording ranges on the user data area, and the data is recorded starting from the recordable position of the selected open recording range.Type: ApplicationFiled: February 27, 2007Publication date: July 12, 2007Inventors: Yong Park, Sung Park

Publication number: 20070159950Abstract: A focus jump technique enables focus control on recording layers of a disc in such a manner that its effect is not absorbed by disturbance or a variation in the movement speed of an objective lens. The technique involves monitoring level of a focus error signal and rejecting noise from the error signal. A speed sensor detects movement speed of an objective lens; and a speed control circuit generates a voltage for controlling the objective lens, based on the detected movement speed. Movement speed of the objective lens is detected during focus jump, a corresponding lens drive signal is generated, and an end position is determined from behavior of the error signal immediately before the end of the jump. A focus control is pulled, from a focus point corresponding to one recording layer, into a focus point corresponding to another recording layer forcibly in a stable manner.Type: ApplicationFiled: March 8, 2007Publication date: July 12, 2007Applicant: HITACHI, LTD.Inventors: Yukinobu Tada, Yoshinori Ishikawa
