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： Embodiments of a data storage tape control system are disclosed that works to prevent or reduce frequency of off-track errors. The invented method slows tape speed in response to the writing head or writing element moving transversely away from a track center a predetermined distance, called an “off-center limit,” wherein the off-center limit is part of the way to an off-track error limit. The off-center limit is close enough to the center of the track that the writing operation is still effective, but wherein further movement out from the center would result in an off-track error and possible overwriting or unreadable data. The tape speed reduction is preferably done in increments until the writing head/element is closer to the center of the track than the off-center limit. Speed reduction is preferably done concurrently with writing, so that writing is not interrupted. Although the tape speed is reduced, the overall efficiency of writing may be increased compared to an operation in which off-track errors and writing failures occur repeatedly, at least in part because of high tape speeds.
