  • Patent number: 6282055
    Abstract: A magnetic tape head assembly for use with a moveable magnetic tape includes an interior tape head module having an interior magnetic gap, and first and second transverse slots disposed on opposite sides of the interior magnetic gap. Each of the transverse slots has inner and outer edges, and the interior module further has first and second slotted regions disposed proximate the outer edges of the first and second transverse slots, respectively. The assembly further includes first and second exterior tape head modules disposed adjacent opposite sides of the interior module. The first exterior module has a first magnetic gap, third and fourth transverse slots disposed on opposite sides of the first magnetic gap such that the fourth transverse slot is disposed between the first magnetic gap and the interior module, and a third slotted region disposed between the fourth transverse slot and the interior module.

  • Patent number: 5953184
    Abstract: A magnetic tape head assembly is provided for use with a magnetic tape storage medium. The assembly includes an interior tape head module having a magnetic gap with transverse slots on each side of the gap which substantially eliminate air and debris entrained between the module and the tape as the tape moves over the module. The assembly also includes a first exterior tape head module on one side of the interior module, the first exterior module having a magnetic gap with transverse slots on each side of the gap and a width greater than that of the interior module. The assembly still further includes a second exterior tape head module on another side of the interior module, the second exterior module having a magnetic gap with transverse slots on each side of the gap and a width greater than that of the interior module. The distances between the magnetic gaps of the modules are each approximately 0.060 inches.

  • Patent number: 5751527
    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.
