摘要： A circuit for a high-density data recording channel includes a first data detector, a second data detector, one or more multiplexers and a sequence identifier. The first data detector generates a first data detector output, and the second data detector generates a second data detector output. The multiplexers change between a first mode and a second mode to alternately receive the first data detector output and the second data detector output. The sequence identifier receives a data sequence including at least one of a first data sequence, such as VFO data, and a second data sequence, such as random data. The second data sequence includes a greater number of signal levels than the first data sequence. The sequence identifier changes the multiplexers between the first mode and the second mode based on whether the data sequence is the first data sequence or the second data sequence. The data sequence includes a plurality of timing stages. The sequence detector can at least partially control a loop bandwidth of the circuit based on the timing stage of the data sequence.

摘要： Method and apparatus for writing timing based (servo) tracks on magnetic recording tape using complementary servo writer pairs. A magnetic tape intended to store, for instance, computer data conventionally contains servo tracks in addition to the data tracks. Typically many servo tracks and data tracks are arranged laterally across the width of the tape. The adjacent servo tracks (bands) here are complementary in terms of the orientation of their stripes and are written (recorded) by a complementary arranged servo writer pair. This advantageously reduces the position error signal by a substantial amount, even to nearly zero. In one version the servo writers are straight in configuration and in another version they are curved or chevron shape. These complementary servo writer pairs write adjacent servo bands. This takes advantage of the fact that typical servo technology, for instance in the LTO tape format, uses two servo heads, a top and bottom servo head, and averages the position error signal of the top and bottom servo read heads in the tape drive to determine the position error. By writing the servo tracks as described here, this error as written-in is substantially reduced. This is because the top and bottom servo sensors interpret the complementary aspect as being position error signal error in opposite directions, which thereby cancels out.

摘要： An example embodiment provides for an apparatus and method, for use in a tape drive system, that supplies tape azimuth error information transduced from servo read elements that are located on differing bumps of a magnetic read/write head. Non-azimuth error information is also transduced from servo read elements located on a read bump. The azimuth error and non-azimuth are utilized to correctly place the magnetic head at a currently selected track of the tape for which data is being written. In one implementation, the servo read elements utilized for transducing the azimuth information are substantially aligned with each other relative to a tape path and disposed on separate bumps. In another implementation, the servo read elements utilized for transducing the azimuth information are not substantially aligned with each other and are disposed diagonally on opposite bumps.

摘要： A method and apparatus for loading tape from a single reel tape cartridge into a take-up reel. The hub filler is securely and releaseably attached to the take-up reel upon the hub filler entering the take-up reel. This attachment provides adequate securement between the hub filler and the take-up reel for the tape to be wrapped around the take-up reel during loading of the tape without the hub filler partially ejecting from the take-up reel. By preventing the hub filler from partially ejecting from the take-up reel, damage to the tape and the tape drive loading mechanism is mitigated. Upon unloading of the tape from the tape drive, the hub filler can be readily released from its attachment to the take-up reel.

摘要： An apparatus for calibrating a tape drive that includes a rotating scanner for reading the tracks on the tape and a tape drive servo for transporting the tape in response to a control signal. The apparatus includes a signal generator and a controller. The signal generator generates an indexing signal based on the rotational position of the scanner. The controller is coupled to the scanner, the tape drive servo and the signal generator, and provides a control signal to the tape drive servo causing the tape drive servo to transport the tape at either above or below a nominal speed. The controller detects an envelope for each of a plurality of scanned signals and the sub code data within each of the scanned signals, determines an envelope measurement for each envelope based on at least one sample magnitude of the envelope and measures a delay time for each of the scanned signals. The delay time is based on the indexing signal and the detection of the sub code data. The controller calculates an optimal delay time by determining when the envelope measurement is substantially at a maximum value based on an approximating function of the envelope measurements and delay times associated with a plurality of scanned signals. The controller changes the control signal so as to direct the tape drive servo to transport the tape at a speed that causes subsequent delay times associated with subsequent scans to be approximately equal to the optimal delay time.

摘要： To control operations of an arcuate scanning head assembly, servo signals are written in one or more designated servo regions along a recording tape, for example along one or both edges of the recording area on the tape. To minimize the space occupied by the servo signals, the servo signals are always written with an azimuth that is substantially parallel to the longitudinal axis of the tape. In the preferred embodiment, servo signals aligned with adjacent tracks are written at two different positions within a servo region. As a read head passes over a track and the servo region, the head should overlap the servo signal aligned with that track and a portion of the servo signal aligned with the adjacent track. A control system samples the signal from the read head in a first time window corresponding to passage of the head across a burst aligned with the track and in a second time window corresponding to passage of the head across a burst aligned with the adjacent track. The system controls one or more parameters relating to the scanning operation as a function of a relationship of the two sampled amplitudes.

摘要： In an arcuate scanner, a read head senses passage over a reference stripe recorded on a moving recording tape. Detection and logic circuitry respond to the read head signal to detect the reference stripe and determine an angular position of the read head with respect to an index associated with the arcuate scanner head assembly. Timing operations of the arcuate scanner and alignment of the arcuate scanner head assembly with regard to an information recording region on the tape are controlled in reference to the detection of the reference stripe.

摘要： A disk drive for a disk file includes means for generating a unique reference position profile for moving the actuator for the servo head over the distance to the target track. The route for the actuator is prescribed and a fixed time period for traversing the distance is prescribed. The control signals control the actuator position not the speed of the motor or the attending velocity feedback loop of prior art systems. The resulting operation is a time optimal, incremental positioning mechanism which eliminates torque and friction problems as well as overshoot and settling problems.
