Patent ID: 8228635

Claim:
A method, comprising: rotating a tape roller barrel by engaging a surface of the tape roller barrel with a longitudinally moving magnetic tape; quenching at least a portion of any air bearing between the moving tape and the barrel surface using grooves formed in the barrel surface; sensing the lateral position of the moving tape; and tilting the rotating tape roller barrel in response to the sensed lateral position of the moving tape to control the lateral position of the moving tape, wherein the tilting includes tilting the rotating tape roller barrel about a pivot disposed at the tape roller barrel wherein said tilting includes driving an electric current conducted by a coil held by a coil holder at least partially disposed within said roller barrel, to generate a magnetic field to tilt said roller barrel and wherein said pivot includes a hinge and wherein said tilting includes pivoting a portion of said hinge disposed in said coil holder to pivot said coil holder relative to a first support frame.
