Magnetic head positioning arrangement

A device for positioning a magnetic head from track to track on a magnetic tape, the device comprising:

• a first plate and a second plate arranged in spaced apart parallelism;
• a first outrigger and a second outrigger connecting said first plate and said second plate;
• a magnetic head assembly having at least one magnetic head and having spaced apart first and second bearing regions on a front surface thereof for sliding on said first outrigger and said second outrigger respectively when said magnetic head is moved from track to track;
• a follower mounted to a back of said head assembly and having exposed threads;
• a threaded shaft arranged behind said magnetic head and spanning between said first plate and said second plate, said threaded shaft rotatable axially and engaged to the exposed threads of said follower;
• and
• a motor means for turning the threaded shaft axially to cause by screw mechanics raising and lowering of said follower wherein said first and second bearing regions comprise a flat bearing surface on one side of said head and a V-shaped channel on an opposite side of said head respectively, said V-shaped channel setting the azimuth and zenith angles of said magnetic head and said V-shaped channel and said flat bearing surface setting the vertical rotation angle of said head with respect to the magnetic tape.

• and
• a motor means for turning the threaded shaft axially to cause by screw mechanics raising and lowering of said follower wherein said outriggers comprise cylindrical columns, and said head assembly further comprises two additional magnetic heads protruding forwardly of said outriggers, said outriggers positioned forwardly to an extent to set the wrap angle of said tape onto said additional magnetic heads by deflecting the tape partially wrapped on said outriggers.

A device for positioning a magnetic head from track to track on a tape, comprising:

• a first plate and a second plate arranged in spaced apart parallelism;
• a first outrigger and a second outrigger connecting said first and second plates;
• a magnetic head assembly having at least one magnetic head, and having on one side thereof two V-shaped guides and on another side a flat bearing surface, said two V-shaped guides receiving said second outrigger, said second outrigger guiding movement of said magnetic head assembly along said second outrigger, and said flat bearing surface pressing and slidable along said first outrigger;
• a means for biasing said magnetic head assembly against said first and second outriggers;
• and
• a means for selectively moving said magnetic head assembly along a length of said outriggers.
