ABSTRACT:
A flying head, helical scan magnetic recording device comprises a tape source, a mandrel for supporting a helical wrap of magnetic tape, a rotor which is lobed with respect to the mandrel axis and a tape sink. The lobed rotor carries one or more magnetic heads at substantially the peak of the lobe around a flying scan path in non-contact, microinch adjacency to the magnetic tape supported on the mandrel. The major portion of the rotor, however, is recessed with respect to the magnetic tape, thereby minimizing the tendency of the tape to shear off the air bearing film carried by the rotor. The result is enhanced dynamic air bearing support of the tape in the immediate vicinity of the flying head.
