摘要： In one aspect, an electromagnetic or capacitive sensing position system for determining the relative position of at least one void in a conductive material is provided. In one example, the system includes a sensor (or probe) having at least two probe elements (e.g., tips or plates). The position of the probe relative to the at least one void is determined in response to an electrical signal (e.g., a differential signal) measured across the two probe elements that varies in response to interaction of the probe elements with the at least one void. The system may be used, e.g., to servo a magnetic head assembly relative to a magnetic storage tape.

摘要： In one example, a method is provided for detecting the relative position of a transducer head with respect to a storage medium utilizing existing or previously written data structures on a magnetic storage tape and optically diffractive media. The method includes generating a read signal from a read element associated with a transducer head, the read signal generated from a reference data track stored on a magnetic storage medium, and determining a relative position of a first diffractive medium with respect to a second diffractive medium, wherein the first diffractive medium is associated with the storage medium. The transducer head is repositioned relative to the storage medium in response to the read signal and the relative position of the first diffractive medium and the second diffractive medium.

摘要： According to one aspect, methods and systems for determining the position of a recording head using existing data structures on magnetic storage media are provided. In one example, a recording head writes data to an active track on a magnetic storage tape, the recording head including a write element and a read element in a known spatial relationship, wherein the read element is configured to access at least a portion of a reference track when the write element is accessing the active track. A controller determines a relative position of the transducer element to the reference track and repositions the recording head to write data to the active track. The read element may be a backward channel reader or dedicated read element of the recording head for reading reference tracks during read and/or write operations.

摘要： 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.
