摘要： In accordance with the present invention, a method of operating a magnetic tape drive, a magnetic tape drive and a servo control system are provided for obtaining and maintaining velocity control in a magnetic tape drive. In one embodiment, a method is provided for operating a magnetic tape drive. The tape drive includes a plurality of DC motors, and each DC motor has a plurality of Hall sensors. The DC motors are under the control of a servo system which is configured to read location information from the magnetic tape, and compute a primary tape velocity from the location information, and sense a secondary and tertiary velocity signal and compute a tape velocity based on one of the sensed secondary velocity signal and tertiary velocity. The method includes detecting if the primary velocity location information is available. In response to detecting that the primary velocity location information is available the primary velocity is employed to control the servo system. In response to detecting the primary velocity location information is unavailable then one of a secondary or a tertiary velocity signal is employed. The secondary velocity signal is employed when an absolute value of a term related to tape velocity is less than a predetermined value. The tertiary velocity signal is employed when the absolute value of the term related to tape velocity is greater than the predetermined value.

摘要： The method employs a servo system for positioning a head laterally to follow lateral motion of a longitudinal tape having longitudinal defined servo track(s), the servo system comprising a servo element configured to sense lateral position of the head with respect to an acquired servo track, a fine actuator configured to translate the head laterally with respect to the longitudinal tape, and a position error signal loop to operate the fine actuator to translate the head laterally to reduce position error. If the servo element is positioned away from the defined servo track(s), a continuous position error offset signal is applied to the fine actuator in a direction towards the defined servo track(s), whereby the fine actuator translates the head in accordance with the continuous position error offset signal; and, in response to the servo system acquiring the defined servo track(s), the continuous position error offset signal is discontinued.

摘要： A video platform architecture provides video processing using parallel vector processing. The video platform architecture includes a plurality of video processing modules, each module including a plurality of processing elements (PEs). Each PE provides parallel vector processing. Specifically, means are provided to read all elements of one or two source vector registers in each PE simultaneously, process the read elements by a set of arithmetic-logical units (ALUs), and write back all results to one of the vector registers, all of which occurs in one PE cycle. To provide such parallel vector processing capabilities, the datapath of each PE is built as a set of identical PE processing slices, each of which includes an integer arithmetic-logical unit (ALU), a vector register bank, and a block register bank. A block/vector register bank holds all I elements of row J in a two-dimensional I×J data blocks for all block/vector registers provided by the architecture.

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.
