摘要： A defect is detected on a storage medium of a disk drive. A location of the defect is determined, within a smallest addressable unit of data stored on the storage medium. An indication of the location is stored in a memory. A location of a sensor of the disk drive relative to the data stored on the storage medium is monitored. A response of at least one of a defect detector of the disk drive, a read channel controller of the disk drive, and a servo controller of the disk drive is changed based on the location of the sensor relative to the data stored on the storage medium and the stored indication of the location of the defect.

摘要： Initial values of shift amounts of a SA amount control device and a FO amount control device are determined as point 'A'; points 'B' and 'C' which are different from point 'A' in x-coordinate are set; a quadratic approximation curve of a performance evaluation value is calculated from performance evaluation values at points 'A' to 'C' and their x-coordinates; point 'D' is set on a straight line 'L' which has a preset slope and passes through point 'A'; points 'E' and 'F' are set by using quadratic approximation curve and a performance evaluation value at point 'D'; a performance evaluation value at point 'J' which is equal to point 'D' in x-coordinate and equal to point 'A' in y-coordinate is calculated on the basis of the quadratic approximation curve; a point 'G' which is equal to point 'D' in x-coordinate and equal to point 'D' in a performance evaluation value on the basis of a preset ratio r1 and a performance evaluation value at point 'J'; an ellipse 50 which passes through points 'D' to 'G' is calculated and its center point 'H' is calculated; and thus SA and FO are adjusted so that a point determined depending on shift amounts of the SA amount control device and the FO amount control device shifts from point 'A' to point 'H'.

摘要： An optical disk playback device comprises first and second lasers, an optical assembly, first and second optical detectors, and controller circuitry coupled to the optical detectors. The optical assembly is configured to direct incident light from the first and second lasers so as to form respective leading and trailing scanning spots on a surface of an optical disk, and is further configured to direct corresponding reflected light from the leading and trailing scanning spots on the surface of the optical disk to respective ones of the optical detectors. The controller circuitry is configured to identify a surface imperfection of the optical disk by processing the reflected light associated with the leading scanning spot prior to the trailing scanning spot reaching that surface imperfection.

摘要： The invention relates to a "jump gap" servo mode provided to position an optical tape medium relative to a pickup head so that tracking may be reestablished after gaps in the servo tracks which occur in the pre- and post-amble fields. These gaps arise periodically because of a seam in the drum used to emboss the servo track on the tape medium. Also disclosed herein are other aspects of optical tape technology, tape manufacturing, and tape usage including: configurations, formulations, markings, and structure of the optical tape; manufacturing methods, systems, and apparatus including curing processes, coating methods, embossing, drums, testing, tracking alignment stamper strip; pick up head adapted for the disclosed optical tape; and optical tape uses including optical storage media devices for multimedia applications.

摘要： An optical information apparatus, comprises an optical pick-up head including: a light source emitting a light beam; a diffraction unit receiving a beam emitted from the light source to generate a plurality of diffracted beams composed of a 0th order diffracted light beam and a 1st or higher order diffracted light beam; a condensing unit receiving the plurality of diffracted beams from the diffraction unit and condensing the beams onto an optical recording medium; a beam splitter receiving the plurality of beams reflected from the optical recording medium and splitting the beams; and a photodetector receiving the beams split by the beam splitter and outputting signals in accordance with amounts of the received light beams, wherein the 0th order diffraction light beam generated in the diffraction unit is set to be a main beam, and two 1st or higher order diffracted light beams generated in the diffraction unit are set to be a first sub-beam and a second sub-beam; the photodetector has a plurality of light-receiving portions; and the main beam, the first sub-beam, and the second sub-beam are received by the plurality of light-receiving portions, respectively. The apparatus further comprises a tracking error signal generator generating a tracking error signal for irradiating a desired track with a beam. Guide grooves are formed on the optical recording medium, the optical recording medium has tracks for recording information, arranged substantially at a constant pitch, and the tracks are provided on the guide grooves or between the guide grooves. An average of the pitch is tp. When the main beam is placed on the track, the first sub-beam and the second sub-beam are respectively placed between the tracks. The tracking error signal generator performs a differential arithmetic operation with respect to signals output from the light-receiving portion receiving the main beam to generate a first push-pull signal, and performs a differential arithmetic operation with respect to signals output from the light-receiving portions receiving the first sub-beam and the second sub-beam to generate a second push-pull signal. An amplitude of the first push-pull signal obtained at the pitch tp when the light beam is scanned in a direction orthogonal to the tracks of the optical recording medium is changed at a pitch different from the pitch tp, due to a fact that a track in which information is not recorded is adjacent to a track in which information is recorded or that a pitch of the track formed on the optical recording medium is partially different from the pitch tp. The first push-pull signal is generated using a polarity or amplification coefficient k different from that of an arithmetic operation for obtaining an ordinary push-pull signal with respect to a region in a vicinity of a center of the main beam. The second push-pull signal is generated using a polarity or amplification coefficient k different from that of an arithmetic operation for obtaining an ordinary push-pull signal with respect to a region in a vicinity of respective centers of the first sub-beam and the second sub-beam. A differential arithmetic operation is performed with respect to the first push-pull signal and the second push-pull signal to generate the tracking error signal.
