摘要： In an essentially flat contour linear tape recording head, a nominal tape wrap angle exists at which reading signals from the magnetic tape ceases and/or commences. This nominal tape wrap angle can be easily determined by monitoring a prerecorded signal, such as the servo track signal, while the tape wrap angle is adjusted. When the signal ceases (or starts, depending upon the direction of adjustment) an initial position of the tape movement control device relative to the tape wrap angle is identified. At this initial position it is known that the tape wrap angle is at its nominal value, such as approximately 0.1°. Thereafter, the tape movement control device can be knowingly adjusted with a calibrated indicator to accurately and quickly achieve a desired final tape wrap angles.

摘要： A tape movement constraint is provided for a tape drive system which moves a tape longitudinally along a tape path across a tape head, the tape having longitudinal tracks. The tape head has a track following servo system for moving the head laterally for following lateral movement of the tracks, where the tape is subject to lateral transient movement. A tape roller bearing closely adjacent the tape head is rotatable about a central axis parallel to the cylindrical peripheral surface, allowing the tape freedom of movement in the longitudinal direction. The tape roller bearing has a frictional cylindrical peripheral surface for contacting and engaging the surface of the tape and constraining movement of the tape in the lateral direction, thereby reducing the rate of the lateral transient movement of the tape to allow the track following servo system to follow the reduced rate lateral transient movement of the longitudinal tracks. Any potential air bearing that could form between the surface of the tape and the surface of the roller bearing is collapsed to insure that the roller bearing frictionally contacts and engages the surface of the tape.

摘要： A read element for a tape drive system is disclosed. The read element generally comprises a magneto-resistive sensor electrically coupled to first and second leads and at least one electrically conductive magnetic shield proximate the magneto-resistive element. A resistor is electrically connected to the conductive magnetic shield and to one or more of the first and second leads. The resistor is disposed between the first and second leads. The resistor continuously discharges electric charge that builds up on the conductive magnetic shield. The resistor typically has a resistance that is large enough to protect against noise due electrical shorting of the conductive magnetic shield and small enough to prevent a build-up of electric charge on the shield.
