  • Patent number: 6480351
    Abstract: The optical servo system for a tape drive that functions to align a read/write head with the data tracks written on a recording surface of a tape by reading optical servo tracks that are formed on the back side of the tape. This process decouples the magnetic recording of data on the recording surface of the tape from the optical servo system which makes use of servo tracks formed on the back side of the tape. The data storage capacity of the tape is increased since the entire recording surface of the tape is filled with data tracks and the precise alignment of the read/write head makes it possible to place the data tracks closer together. Regions of contrasting reflectivity or phase are also provided on a surface of the read/write head to enable the optical servo system to view an image of both the read/write head and the entire back side of the tape to thereby align the movable read/write head with the data tracks.

    Abstract: An imaging system for forming multiple superimposed image exposure frames on a photoconductive member moving in a process direction including a rotating polygon having a plurality of facets. A raster output scanner forms a plurality of scanlines in a transverse direction across the photoconductive member by reflecting modulated beams from the rotating polygon. A control provides a start of scan (SOS) signal for each of the facets of the rotating polygon, determines the facet related to the first scanline of a first image exposure frame on the photoconductive member, and initiates the first scanline of each succeeding superimposed image exposure frame on the photoconductive member in relation to the facet related to the first scanline of the first image exposure frame.

  • Patent number: 5633747
    Abstract: An apparatus for both deflecting a beam of light illuminating a spot on a surface and varying the size of the spot, electronically, without changing any system components. The apparatus includes an acousto-optic deflector driven with a linear FM signal produced by a chirp signal generator. The linear FM signal is characterized with a dispersion rate, and the chirp signal generator includes a chirp dispersion selector to vary the dispersion rate. A beam of collimated light passes through the acousto-optic deflector and appropriate focusing optics image the beam onto a spot in a nominal focal plane. The chirp dispersion selector sets the dispersion rate in accord to a nominal rate, resulting in the beam illuminating a spot in the focal plane. Generally, the focal plane coincides with a wafer surface, of the type having periodic and non-periodic features on it. The spot size may be varied from that of a diffraction limited spot to a spot whose maximum size is system dependent.

  • Patent number: 5633851
    Abstract: A scanning device for repeatedly scanning a scanning surface of a record carrier (e.g., a tape) by means of a first and a second scanning spot produced by respective scanning beams. The scanning spots perform synchronous movements along a first and a second scanning path, respectively, having different given scanning directions, as a result of which, the distance, viewed in a direction transverse to the scanning paths, between the first and the second scanning spot changes during scanning. The scanning device can be used in a recording and/or read apparatus which further includes a detection system for converting radiation emanating from the second scanning spot into a corresponding detection signal, and a measurement circuit which derives a position measurement signal indicative of deviation of track pitch based on a deviation in a relationship between the detection signal and a reference signal indicative of the position of the first scanning spot on the first scanning path.

  • Patent number: 5617391
    Abstract: An optical recording and reproducing system has an optical recording and reproducing head driving arrangement including an optical pick-up and has an optical recording medium provided between the recording heads. The optical recording and reproducing head is mounted on a rotating arrangement. The head scans tracks while a relative position of the recording medium and rotating arrangement is changed. Each track has an address recorded at the beginning of scanning and a hold signal at the end of scanning. The recording and reproducing heads are separated one track. The recording head makes recording while the reproducing head makes reproduction. In the recording or reproducing mode of operation, the track address is looked. If wrong, it is corrected. The hold signal is detected to operate a tracking device and focusing device. Scanning the next track is determined by the address before tracking is made for recording or reproduction.

  • Patent number: 5604838
    Abstract: The present invention relates to video recording and playback techniques and devices which create relative movement between a laser and an optical medium such as a flexible optical tape to permit recording of relatively high bandwidth signals. Further, the present invention relates to video recording and playback techniques and devices which optimize relative movement between a laser source and the optical medium in a cost-effective manner. Data spots having a set of predetermined feature sizes (i.e., set of varying hole sizes) can thus be recorded at a rate useful for high bandwidth signals (e.g., television video signals). Further, recording on a flexible optical medium (e.g., optical tape) can be performed in a manner which optimizes space efficiency on the tape.

  • Patent number: 5600617
    Abstract: A data recording device for a motion picture film is provided in which one ends of plural optical fibers are connected to light emitting devices and the other ends of the optical fibers are arrayed in accordance with a dot pattern of audio data to be recorded. The light emitting diodes are turned on responsive to the audio data to be recorded on the motion picture film. The audio data carrying light, produced by the turning on of the LEDs, is conducted via the optical fibers to a head unit so as to be radiated on the motion picture film via a radiating port of the head unit. By the above arrangement, the optical fibers may be arrayed optionally at the head unit without regard to the array of the LEDs. Consequently, the LEDs are affected to a lesser extent by heat evolved on turning on the LEDs. By linearly arraying the optical fibers at the head unit 1, a larger quantity of audio data may be recorded on the motion picture film.

  • Patent number: 5559766
    Abstract: An optical recording method and an optical recording apparatus enable recording information on recording tracks substantially corresponding to ideal reference tracks, on an optical recording medium without preformatted tracks. The optical recording medium is scanned by a rotating optical scanning system using a scanning light beam emitted by an external light source to record information on the optical recording medium. Prior to recording the information on the optical recording medium, information recorded on a reference track recording medium provided with ideal reference tracks is reproduced in a tracking control mode to acquire tracking control data and the tracking control data is stored in a waveform memory. In recording information on the optical recording medium, the rotating optical scanning system is controlled on the basis of the previously stored tracking control data so that the scanning spot traces recording tracks corresponding to the ideal reference tracks.
