Abstract

A multi-gap magnetic head is movably mounted on the central link of a double-parallelogram. The head is adapted for transverse movement relative to a length of magnetic recording tape. This transverse movement is controlled by a linear motor which connects to this central link. Fig. 1 is a perspective view, whereas Fig. 2 is a front view. Head 10 includes a number of transducing read/write gaps, for example, nine, located on gap line 11. Head 10 is mounted to the central link 12 of a double parallelogram made up of metal spring blades 13 and 14. Each of the blades 13 and 14 includes an offset or bent portion 15. The ends of blades 13 and 14 are rigidly attached at 16. A length of one-half-inch-wide magnetic recording tape (not shown) runs past head 10, as the tape is guided by rollers 17 and guide blocks 18.

Head Mount

A multi-gap magnetic head is movably mounted on the central link of a double- parallelogram. The head is adapted for transverse movement relative to a length of magnetic recording tape. This transverse movement is controlled by a linear motor which connects to this central link. Fig. 1 is a perspective view, whereas Fig. 2 is a front view. Head 10 includes a number of transducing read/write gaps, for example, nine, located on gap line 11. Head 10 is mounted to the central link 12 of a double parallelogram made up of metal spring blades 13 and 14. Each of the blades 13 and 14 includes an offset or bent portion 15. The ends of blades 13 and 14 are rigidly attached at 16. A length of one-half-inch-wide magnetic recording tape (not shown) runs past head 10, as the tape is guided by rollers 17 and guide blocks 18. This tape contains, for example, eighteen parallel data tracks. Nine of these tracks are simultaneously accessed by head 10 when the head is in a first position. The other nine tracks are accessed when the head is moved to its second position. When it is necessary to transduce the other nine data tracks, linear motor 19 (Fig. 2) exerts a force on link 12, and head 10 is moved to the second position, transverse the length of tape. The double parallelogram insures that such movement occurs without skew of the head's gap line 11. Preferably, the movable central link 12 includes a pair of tape guide channels 20.
