Abstract

This skew adjusting mechanism mechanically adjusts the position of magnetic head 1 and its head gaps 2, relative to moving magnetic tape 3. Adjustment is achieved by the simultaneous rotation of two tapered and threaded plugs 4 and 5 which mate with tapered and threaded split-holes 6 and 7 formed in metal head support 8. This support has its bottom surface, opposite the head, fixed to the frame of a magnetic tape unit. Each plug is tapered inwardly toward the center of the support. One plug is metal and the other is plastic so that constant tension is maintained during travel of the plugs. Due to the large mechanical advantage, no locking devices are required.

Skew Adjusting Mechanism

This skew adjusting mechanism mechanically adjusts the position of magnetic head 1 and its head gaps 2, relative to moving magnetic tape 3. Adjustment is achieved by the simultaneous rotation of two tapered and threaded plugs 4 and 5 which mate with tapered and threaded split-holes 6 and 7 formed in metal head support 8. This support has its bottom surface, opposite the head, fixed to the frame of a magnetic tape unit. Each plug is tapered inwardly toward the center of the support. One plug is metal and the other is plastic so that constant tension is maintained during travel of the plugs. Due to the large mechanical advantage, no locking devices are required.

The plugs are rotated simultaneous and caused to travel in the same, direction as hexagonal shaft 9 is rotated. This shaft freely passes thru hole 10 formed in the support. Clockwise rotation of the shaft causes both plugs to move to the left. The head then pivots counterclockwise as the support flexes and pivots about its thin midsection 11.
