摘要： Methods and apparatus for a magnetic tape drive, which allow a magnetic tape to be positioned with respect to a tape head. The invention includes actively controlling the position of a tape guide used to support the tape as it passes over the tape head. By controlling the position of the tape guide, the tape can be caused to move a direction perpendicular to the primary direction of travel of the tape. One method of the invention includes providing a first tape guide aligned along a primary axis and disposed proximate a first side of the tape head. The tape is moved across the first tape guide and the tape head in a primary direction while the first tape guide is pivoted, to thereby cause the tape to move in a secondary direction essentially perpendicular to the primary direction. Alternately, or in addition to the step of pivoting the first tape guide, the method can include the step of translationally moving the first tape guide along the primary axis while moving the tape across the first tape guide and the tape head. The apparatus of the present invention can include one or more tape guides which support a tape as it moves across a tape head. Each tape guide can be configured to tilt or move translationally, or to do both, to cause the tape to move in a direction perpendicular to the primary direction of transport of the tape across the tape head.

摘要： A rotary actuator disk drive in which the rotary actuator is driven by a motor comprising a movable coil and a stationary permanent magnet structure producing a magnetic field which links the coil. The rotary actuator comprises a load beam arm stack and a voice coil arm of electrical insulating material such as a light weight plastic, all of which are axially stacked and swaged to a rotary actuator bearing hub which is rotatably mounted in the disk drive. The coil arm of electrical insulating material has a bobbin section on which the coil is directly wound. The coil arm is molded together with the coil arm mounting bushing, a latch pin of magnetic material and an actuator arm balance weight insert molded therein. The latch pin is linked by the permanent magnet field of the motor permanent magnet structure and functions with that structure to define mechanical limits of angular actuator movement and to magnetically latch the actuator in one angular limit when the disk drive is not in use. Latch release is achieved by subjecting the rotary actuator to several cycles of oscillation at substantially the resonant frequency.

摘要： An example tape drive includes a magnetic tape head, an actuator, and a controller. The magnetic tape head includes a data write element to write a data track including data onto magnetic tape. The data track includes a non-trimming portion and a trimmable portion. The magnetic tape head also includes a data read element to read the data written to the non-trimming portion of the data track to verify the accuracy of the data. The controller positions the magnetic tape head via the actuator to allow (i) the data write element to write the first data track, and (ii) the data read element to read the second portion of the first data track. From the read data, a determination may be made as to whether the data was written to the non-trimming portion of the data track with a threshold level of accuracy.

摘要： A method, apparatus, and program product stream data between a host element and a target element in a parallel computing system. The method comprises partitioning data used to perform a task into a plurality of data streams based at least in part upon data associated with the task and partitioning a data stream into a plurality of data stream views based at least in part on a memory size associated with a target element configured to process the data stream. The method further comprises sequentially communicating at least a portion of the data stream views to the target element via a data streaming infrastructure implemented on at least a host element and the target element, wherein the portion of the data streaming infrastructure on the host element transfers the portion of the data stream views to the portion of the data streaming infrastructure on the target element.

摘要： Embodiments of a data storage tape control system and methods are disclosed that may work to correct off-track errors, reduce the frequency of off-track errors, and/or reduce the negative effects of off-track errors in writing performance. The invented method slows tape speed in response to off-track errors, preferably by continuously decelerating while attempting writing multiple retries. The invented method helps prevent further off-track errors and the resulting frequent interruptions of writing, by helping improve head placement accuracy. Once a selected amount of data is written, for example, a standard data-set or other block of data, the tape speed optionally may be accelerated to the original target speed. While the average tape speed may be reduced during the invented writing procedure, the overall efficiency of writing may be increased compared to an operation in which off-track errors and writing failures occur repeatedly because of high tape speeds.
