Abstract
A system, according to one embodiment, includes: a module having transducers positioned along a tape bearing surface of the module, and a roller guide. A patterned bar is also positioned relative to the roller guide and module to engage a magnetic tape. Moreover, the patterned bar has a plurality of recessed regions along a tape bearing surface thereof. The patterned bar is also not directly coupled to the module, and both edges of the patterned bar which engage the magnetic tape are skiving edges. Other systems, methods, and computer program products are described in additional embodiments.
Claims17
A system, comprising:
- a module having transducers positioned along a tape bearing surface of the module;
- a first roller guide;
- and
- a first patterned bar positioned relative to the first roller guide and module to engage a magnetic tape,
- wherein the first patterned bar has a plurality of recessed regions along a tape bearing surface thereof,
- wherein the first patterned bar is not directly coupled to the module,
- wherein both edges of the first patterned bar which engage the magnetic tape are skiving edges,
- wherein a longitudinal axis of each of the recessed regions is about parallel to an intended tape travel path,
- wherein a wrap angle of the magnetic tape relative to the tape bearing surface of the patterned bar is greater than 0°.
A system, comprising:
- a module having transducers positioned along a tape bearing surface of the module;
- a first pair of guides positioned on a first side of the module along an intended tape travel path;
- a first patterned bar positioned between the first pair of guides;
- a second pair of guides positioned on a second side of the module opposite the first side along the intended tape travel path;
- a second patterned bar positioned between the second pair of guides;
- and
- wherein the first and second patterned bars each have a plurality of recessed regions along tape bearing surfaces thereof,
- with a proviso that a tape bearing surface of each of the guides is not textured.
