Abstract

A magnetic head may be mounted to a tape drive by the use of a ball joint to adjust for skew and roll. Articulation of the ball joint is controlled by differential screws. The differential screws move tilt rings radially to the ball. Troughs formed in the head and drive mounted cones keep each tilt ring from off-tracking.

Magnetic Head Mounts

A magnetic head may be mounted to a tape drive by the use of a ball joint to adjust for skew and roll. Articulation of the ball joint is controlled by differential screws. The differential screws move tilt rings radially to the ball. Troughs formed in the head and drive mounted cones keep each tilt ring from off-tracking.

As shown in Fig. 1, a magnetic head 10 is fastened to a top cone 11 by screws 12. A bottom cone 13 is fastened to the base plate 14 of the tape drive. A ball 15 meets with the top cone 11 and the bottom cone 13. The ball 15 is held to the bottom cone 13 by a cap 16. A bolt 17 fastens the top cone 11 to the ball 15.

Differential screws 18, four shown spaced 90 degrees apart, are threaded to the ball 15 through the cap 16. Tilt rings 19 are threaded to each of the free ends of the differential screws 18. The tilt rings 19 fit into troughs 20 spaced 90 degrees apart around the circumference of the bottom cone 13 as well as troughs (not shown) in the top cone similarly spaced around the circumference of the top cone 11.

Articulation of the ball 15 is controlled by the differential screws 18. The roll and skew adjustments are independently performed by rotating the differential screws. The roll and skew adjustments can be executed independently because the axis of each pair of the differential screws 18 and tilt rings 19 are orthogonal to the other pair. As the differential screws 18 are rotated, the tilt rings 19 will move radia...
