Abstract: PURPOSE:To easily read the address information and to improve the SN ratio of the sound by detecting the reflecting beam of the laser beam to focus at the track for the address on the optical disk out of a pair of laser beams for tracking and decoding the address information. CONSTITUTION:The device has the guide groove for tracking, one side, in which the address information is recorded, is used as the track for the address and other side is used as the data track to record the data. A pair of laser beams is irradiated at the interval of the odd number times of approximately 1/2 of the track pitch through an objective lens 55 to an optical disk 40. A pair of the reflecting beams from the optical disk 40 is made incident on a pair of light detecting elements 20 and 22 divided into two respectively, from the difference in respective difference outputs of both respective detecting outputs, the tracking error signal is obtained and the tracking is controlled. Out of a pair of light detecting elements 20 and 27 divided into two, the address information is decoded from the output of the light detecting elements divided into two on which the reflecting beam from the track for the address is made incident.

Abstract: PROBLEM TO BE SOLVED: To prevent a digital binary signal from being copied as it is. SOLUTION: The input digital data from an input terminal 11 are processed by respective circuits 13-16 to be modulated by a modulation circuit 17, and when a synchronizing signal is added to them by a synchronism addition circuit 18, the synchronizing signal is added at a synchronous format not used usually different from a beforehand standardized synchronous format, e.g. by changing a synchronous pattern from a normal synchronous pattern, or changing the position of the synchronizing signal from a normal position. When the digital binary signal of such a synchronous format is intended to be copied as it is, the copy is prevented by that the synchronism comes off, etc.

Abstract: PROBLEM TO BE SOLVED: To provide an optical disk drive that calculates a tilt angle of an optical disk with a simple configuration and to provide a tilt angle detecting method. SOLUTION: An error phase difference ΔDP between a PPe signal and a DPD signal, changes according to a tilt amount θ, which is a tilt angle of an optical disk, the PPe signal being a push-pull signal generated by utilizing a fact that a difference in light quantity of two overlapped regions W changes according to displacement of radiation of an optical beam toward a desired track in the optical disk, and the DPD signal being a second signal generated by utilizing a fact that light quantity distribution is changed in the overlapped regions W according to the displacement of radiation. Based on the error phase difference ΔDP, the tilt angle as a tilt amount θ is calculated. COPYRIGHT: (C)2009,JPO&INPIT
