摘要： In one embodiment, a tape movement constraint for a tape drive system, comprises a tiltable tape roller bearing having a roller barrel biased in a first position on a pivot axis, using magnetic attraction between a movable magnet and a return path structure of magnetically permeable material. The roller barrel is pivoted on the pivot axis by conducting current through a fixed coil to generate a magnetic field which is conducted by the return path structure to interact with the magnetic field of the magnet. At least a portion of any air bearing between the moving tape and the barrel surface is quenched using grooves formed in the barrel surface. Other embodiments are described and claimed.

摘要： A tape movement constraint for a tape drive system, comprises a tiltable tape roller bearing having a grooved surface adapted to contact and engage a surface of the tape as the roller barrel rotates, and an actuator adapted to pivot the roller bearing surface when the actuator is actuated, to control the lateral position of a tape. In operation, in one embodiment, a roller barrel of the tiltable roller bearing is biased in a first position on a pivot axis, using magnetic attraction between a movable magnet and a return path structure of magnetically permeable material. The roller barrel is pivoted on the pivot axis by conducting current through a fixed coil to generate a magnetic field which is conducted by the return path structure to interact with the magnetic field of the magnet. Other embodiments are described and claimed.

摘要： In one embodiment, a tape read/write head supported by a lever is biased in a first position, using magnetic attraction between a magnet supported by the lever, and a return path structure of magnetically permeable material. In the illustrated embodiment, the magnet centers itself, in the absence of a coil generated magnetic field, in the middle of a gap of the magnetic return path structure. In one aspect, the mass of the read/write head and one side of the lever may be balanced by the mass of the magnet and the other side of the lever. The lever and hence the tape read/write head carried by the lever, may be pivoted by conducting current through a coil to generate a magnetic field which is conducted by the return path structure to interact with the magnetic field of the magnet. As a consequence, the lever pivots on a pivot axis as a function of the magnitude and direction of the current through the coil. The face of the magnet may be divided into portions of opposite magnetic polarity to facilitate a relatively pure torque to be developed substantially without a net force. Other embodiments are described and claimed.

摘要： A mechanical linkage, including a worm gear and a worm gear support bracket, for joining a drive motor to a helical gear; it is particularly adapted for controlling a tape drive head. The worm gear head is threadably engaged with the helical gear. The shaft of the worm gear is engaged with the motor and is sufficiently flexible to operably correct misalignments between the worm gear shaft and the motor shaft. The support bracket includes a flat leaf spring which provides lateral spring force against the worm gear shaft to maintain a driving engagement between the worm gear and the helical gear, while the leaf spring is stiff in the in-plane directions of movement. The support bracket also includes a bushing, such as a C-shaped bushing or a cylindrical bushing, which provides support for the worm gear shaft against the helical gear.
