  • Optical apparatus for tracking a magnetic tape
    Patent number: 7149049
    Abstract: An optical tracking system is presented which aligns a recording head with a magnetic tape. The system relies on an optically detectable servo track on the back of the tape. The servo track is formed by repeatedly engraving, at spaced intervals, three co-linear marks perpendicular to the length of the tape. Laser light reflects off the marks, and passes through a ball lens that directs the reflected light on to separate light detectors, one for each mark. By recording characteristics of the reflected light, the detectors transmit information to the system that permits the recording head to be properly aligned with the tape.
    Type: Grant
    Filed: May 23, 2003
    Date of Patent: December 12, 2006
    Assignee: Quantum Corporation
    Inventors: George A. Saliba, Hong Chen, Joseph Panish, Leo Cappabianca, Richard Gulbankian

  • Optical apparatus for tracking a magnetic tape
    Patent number: 6246535
    Abstract: An optical tracking system is presented which aligns a recording head with a magnetic tape. The system relies on an optically detectable servo track on the back of the tape. The servo track is formed by repeatedly engraving, at spaced intervals, three colinear marks perpendicular to the length of the tape. Laser light reflects off the marks, and passes through a ball lens that directs the reflected light on to separate light detectors, one for each mark. By recording characteristics of the reflected light, the detectors transmit information to the system that permits the recording head to be properly aligned with the tape.
