Abstract

With increasing track density in magnetic tape drives and the need to simultaneously read or write on a plurality of tracks, it is sometimes necessary to provide more than one read/write head module. It is essential that each head module be aligned with each other head module. The structure shown in the figure provides a dual head mount for adjustably aligning and mounting two head modules. Recording heads 3 and 4 are mounted on each side of the central leg of head mount 1. The heads 3 and 4 are pivotally attached to the base portion of mount 1 at pivot points B and C, respectively. Head mount 1 is pivotally attached to a base plate 2 at pivot point A. Mounting screw 5holds the mount 1 on base plate 2.

Dual Head Mount

With increasing track density in magnetic tape drives and the need to simultaneously read or write on a plurality of tracks, it is sometimes necessary to provide more than one read/write head module. It is essential that each head module be aligned with each other head module. The structure shown in the figure provides a dual head mount for adjustably aligning and mounting two head modules. Recording heads 3 and 4 are mounted on each side of the central leg of head mount 1. The heads 3 and 4 are pivotally attached to the base portion of mount 1 at pivot points B and C, respectively. Head mount 1 is pivotally attached to a base plate 2 at pivot point A. Mounting screw 5holds the mount 1 on base plate 2. The heads 3 and 4 are laterally adjusted by means of a differential screw mechanism D which rotates the head mount 1about pivot A. The rotation caused by mechanism D moves heads 3 and 4 laterally. The skew of heads 3 and 4 is adjusted individually by differential screw mechanisms E and F, respectively. Head 3 is rotated about pivot B by mechanism E, and head 4 is rotated about pivot C by mechanism F. When adjusting the heads, the lateral adjustment should be made and then followed by the skew adjustment since the skew adjustments have little effect on the lateral adjustments. When the heads are properly adjusted, a clamping device is fitted to the recording heads 3 and 4 to hold them in position on the head mount 1.
