摘要： Operations include compensating for a Tracking Error Signal (TES) offset in an optical tape drive. The tracking error offset compensation system detects a control signal for controlling movement of an optical head across a surface of a tape. The tracking error offset compensation system computes an estimated movement of the optical head, based on the initial control signal. The tracking error offset compensation system determines an estimated TES offset, based on the estimated movement of the optical head. The tracking error offset compensation system uses the estimated TES offset to correct a TES. The tracking error offset compensation system transmits the corrected TES, for controlling additional movement of the optical head.

摘要： An information recording and playback device includes a recording and playback unit, and a controller. The controller divides a recording area of an optical disk into a first recording area which is at an inner circumference side, and a second recording area which is at an outer circumference side. The controller controls the recording and playback unit such that the unit records or plays back data in the first recording area at a first speed, and records or plays back data in the second recording area at a second speed slower than the first speed. The predetermined radius is set to a boundary between an area in which a control residual exceeds a predetermined reference value when servo control related to focusing and tracking is performed on the recording area of the optical disk, and an area in which the control residual does not exceed the predetermined reference value.

摘要： In an optical disc apparatus for reproducing information recorded on a track of an optical disc, an optical head irradiates a light beam onto the track, detects a reflected light reflected by the track, and generates a reproduction signal based on the reflected light. A decoder circuit decodes the reproduction signal, and generates a decoded signal including information recorded on the track. A correlation detector circuit calculates a cross-correlation value between the reproduction signal and the decoded signal. A servo circuit detects a deviation amount of an irradiation position of the light beam onto the track, from the reproduction signal, and controls the irradiation position of the optical head based on the cross-correlation value and the deviation amount.

摘要： An optical disk drive and a digital servo method for the optical disk drive includes controlling functions of the optical disk drive with a microprocessor. Low-pass filtered and gain adjusted versions of individual photodetector output signals resulting from an illumination of an optical disk are received. Versions of the individual photodetector output signals are digitized to produce digital signals. A focus control signal and/or a tracking control signal is determined through at least one servo algorithm executed by a digital signal processor based on a focus error and/or tracking error, respectively, determined from the digital signals. The digital signal processor is an integrated circuit structured and arranged for manipulation of digital signals in accordance with programmed commands, and in a manner that operates faster than the microprocessor.

摘要： In recording and reproducing devices that use angular-multiplexing holography, accessing a recorded hologram of interest had taken time because after positioning at the vicinity of the hologram, it had been necessary to carry out fine adjustment of the position while checking the signal quality of the hologram. The optical information recording and reproducing device according to the present invention uses angular-multiplexing to record interference patterns formed from a signal beam and a reference beam onto an optical information recording medium as page data and reproduces information from the optical information recording medium, said optical information recording and reproducing unit being provided with: a light-source unit that outputs light; an optical splitting unit that splits the light into a reference beam and a signal beam; an angle controlling unit that controls the angle for the direction of angle multiplexing at which the reference beam enters the optical information recording medium; an optical detecting unit that detects a reproduced image that is reproduced by using the reference light; and a position control unit that controls the position relationship between the reference beam and the optical information recording medium. The device treats a set of page data as a book, and during recording, at least a portion of the page data in adjacent books is recorded while the entrance angle for the direction of angular-multiplexing for the reference light is shifted by means of the angle controlling unit. During reproduction, at least a portion of the light amount of a reproduced image is detected by using the optical detecting unit, and the position of the book is detected on the basis of information about the detected light amount.
