ABSTRACT:
A housing apparatus is operable to align a record/playback head with respect to different parallel tracks on a moving magnetic tape in such a manner as not to disturb the positioning of the tape as it passes longitudinally along its transport path. The housing apparatus includes a housing body having a convex, rounded front face lying in contacting relation with respect to the moving magnetic tape at two closely spaced-apart areas. A record/playback head is transversely movable with respect to the housing body and extends through a provided opening in the body to lie in contact with the moving tape between the two tape contacting areas of the housing body front face. Means is provided to move the record/playback head transversely with respect to the tape while the moving tape is in contact with these two areas on either side of the head.
