摘要： In a tape having separate servo bands of patterns positioned laterally across the tape, the patterns of a separate servo band have at least one differentiating characteristic with respect to patterns of another of the separate servo bands. The differentiating characteristic allows identification of the separate servo bands. For example, the patterns of a separate servo band have differing azimuthal orientations of detectable transitions with respect to another servo band, such as being laterally inverted. In another, variations in the width of gaps of patterns are made with respect to another servo band. In another, variations are made in the number of the detectable transitions of patterns with respect to the patterns of another servo band.

摘要： To detect alignment and/or absence of a tape leader pin in an opening of a tape cartridge, a light source scans the opening. Detection logic analyzes the detected reflection waveform signal for deviation from a cylindrical surface reflection of the tape leader pin, if any, such as elliptical or conical, representing tilt angle misalignment of the pin. Further, both ends of the pin are scanned for difference in displacement and for difference in amplitude, displacement representing tilt in the direction of scan, and amplitude representing that one end or the other is likely to have been pulled into the cartridge. Low amplitude of both represents absence of the pin.

摘要： An apparatus, system, and method are disclosed for the velocity proportional clocking of time base servo tape storage devices. The apparatus, system, and method allow the velocity of time base servo tape storage devices to be adjusted and maintained by adjusting the frequency of a clock. In one embodiment, a velocity command is received and the clock signal frequency is varied in response to the command. A feedback control signal may then be produced to control the velocity of a time base servo device in response to the clock signal frequency, the feedback control signal being used to vary the velocity of a servo motor. In one embodiment, the velocity of the servo motor varies directly proportionate to the clock signal frequency.

In another embodiment, the magnetic head element comprises a read transducer formed of a thin film magnetoresistive sensor coupled to a magnetic flux guide in a trench formed on the transducing surface of a substrate. According to the method for manufacturing an embodiment of the servo verifier read head for magnetic tape recording, a plurality of trenches are formed in a nonmagnetic substrate wafer, preferably, a ceramic wafer. A first magnetic permeable layer is deposited in the trench. A first insulating layer is deposited on the first magnetic permeable layer. A conducting circuit is defined on the first insulating layer such as by lithographically defining the circuit. A second insulating layer is deposited in the trench such that the conducting circuit is enclosed between the first and second insulating layers. The wafer can be planarized down to about the original surface level of the wafer. A pattern of read gaps is defined and a second magnetic layer is added over the second insulating layer.

摘要： In magnetic tape having separate longitudinal servo bands of servo information with superimposed data information, the separate servo bands have selected different superimposed data information, to identify the separate servo bands for independent addressability. The servo information comprises non-parallel laterally extending transitions to indicate lateral positioning, and the selected different superimposed data information may comprise a lack thereof in portion(s) of the servo bands. Where the superimposed data information is longitudinal position information of the tape, the selected different superimposed data information may comprise different longitudinal position information of one or more servo band(s). The selected different superimposed data information may comprise a band identifier in the superimposed data information of one or more of the servo bands.

摘要： Provided are techniques for determining a reel motor angle. An estimate of an interval to degrees translation factor that represents a measurement angle interval divided by a first pulse count is calculated, wherein the first pulse count represents format transitions counted during an angular measurement interval. A reel motor angle is determined using the estimate by: receiving an indication that a rotating reference point has crossed a stationary reference point, wherein the indication is recognized as indicating that an angle between a motor rotor and a motor stator is a reference angle; determining a second pulse count, wherein the second pulse count represents format transitions counted since the indication was received to a given point in time; and at the given point in time, multiplying the second pulse count by the estimate to generate a first value and adding the reference angle to the first value to generate the reel motor angle.
