Abstract
A magnetic tape head assembly with enclosed through slots to eliminate an air bearing at high tape speeds and lower operating tape tensions is provided. In one embodiment of the present invention, the magnetic tape head comprises a recording gap, containing read/write elements, across the width of the head and slots exposed to the tape head surface that faces the plane of the tape. These slots run through the head approximately perpendicular to the plane of the tape and are open to ambient pressure at a tape head surface other than the surface facing the plane of the tape. These slots are aligned with the read/write elements along the recording gap.
