ABSTRACT:
A magnetic-tape-cassette apparatus having a magnetic head fixed in a head mount and carried on a head mounting plate. The head mount includes a cylindrical tape guide disposed to each side of the magnetic head air gap, in the direction of tape travel, a height limiter at one axial end of each guide surface, and an obliquely disposed control surface at the other end of each guide surface for biasing magnetic tape against the height limiters, so that the magnetic tape always has a constant orientation with respect to the air gap.
