ABSTRACT:
An improved magnetic tape head contour for reading from and writing to magnetic tape moving across the tape head has a unique configuration of bleed slots such that land width is limited to a width that optimizes flying height at increased tape speeds on the order of 4 meters/second. The number of bleed slots is increased to minimize tape undulations thereby minimizing tape head wear profile undulations. A single gutter slot is optionally provided at each end of the tape head to reduce end element wear and increase the useful life of the heads.
