ABSTRACT:
A switching plate includes a cam portion engaging a head moving plate for moving a head on an axis normal to a tape surface during a shifting operation so as to retract the head from the tape during shifts between forward and reverse to prevent surface damage to the tape. The switching plate carries a head driver having tapered ridges upon which a head holder rests. The head holder is movable on an axis parallel to the widthwise direction of tape. Shifting of the switching plate drives the head holder to rest upon elevated ridges for reverse mode operation or upon a second surface for forward mode operation.
