Abstract
Abstract Skew adjusting apparatus for a magnetic tape unit includes a right angle mounting plate for the magnetic head with one surface being curved with a radius of curvature having a center line coincidental with the center line of the tape path. The curved surface is biased toward two guiding pins. The mounting plate moves with the curved surface riding on the pins so that the magnetic head is rotated about the center line of the tape path.

Skew adjusting apparatus for a magnetic tape unit in which a magnetic tape is driven along a tape path comprising: a magnetic tape head, a mounting plate, said magnetic head being mounted on one surface of said mounting plate, another surface of said plate being curved with a radius of curvature having a center line coincidental with the center line of said tape path, said mounting plate having a notch in the other surface thereof, guide means mounted on said magnetic tape unit for guiding the curved surface of said plate in movement which rotates said magnetic tape head about a point which lies in the center line of said tape path, a vernier screw threadably mounted on said magnetic tape unit, said mounting plate having a surface which is angled to bear against an end of said vernier screw, rotation of said vernier screw causing movement of said mounting plate so that said head rotates about said center line of said tape path, and a spring having one end disposed in said notch for biasing said mounting plate toward said vernier screw.
