Abstract
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.
