ABSTRACT:
A carrier for mounting a pair of magnetic heads to a rotatable head drum section of a helical-scan magnetic tape unit includes two head mounting pads held in a spaced-apart relationship by one or more C-shaped flexible connecting sections. The pads preferably have opposed edges which are arranged to define a reference direction perpendicular to the axis between the head gaps (head pair axis). With this configuration, head protrusion may be independently adjusted by flexing the C-shaped section and, using such opposed edges for reference, dihedral correction (to align the head pair axis with the drum rotary axis) may be made without disturbing head protrusion.
