摘要： In one general embodiment, a method includes determining a distance from a transducer of a module to an edge of the module closest thereto, and selecting a wrap angle based on the determined distance for inducing tenting of a moving magnetic recording tape in a region above the transducer. In another general embodiment, a method includes running a magnetic recording tape over a tape bearing surface having at least one edge, and detecting signals from the tape at differing wrap angles for estimating a height of tenting of the tape above a transducer at each of the wrap angles. A wrap angle is selected to provide about a predefined height of tenting of the tape above the transducer.

摘要： A system, according to one embodiment, includes: a main pole; and a trailing shield. A first distance D1 is defined in a track direction between the trailing shield and a pole tip region of the main pole; and a second distance D2 is defined in the track direction between the trailing shield and a second region of the main pole located behind the pole tip region, where D2 is greater than D1. Other systems, and methods are described in additional embodiments.

摘要： An apparatus according to one embodiment includes a module having a substrate, read and write transducers positioned towards a media facing side of the module, and a closure. The write transducers include write poles having media facing sides with zero or near-zero recession from a plane extending along the media facing side of a substrate of the module. The read transducers each have two shields. Media facing sides of the two shields are recessed a same amount from the plane, and are more recessed from the plane than the write poles.

摘要： A unidirectional and bi-directional tape head with sub-ambient pressure cavities. The tape head is adapted for reading and/or writing to a magnetic tape. The tape head includes: a tape-bearing surface; a transducer area, having at least one transducer designed for reading and/or writing to the magnetic tape; a cavity open on the tape-bearing surface adjacent to the transducer area that extends parallel to the transducer area and transversally to the longitudinal direction of circulation of the tape such that an opening of the cavity faces the tape in operation; and one or more air bleed slots connected to the cavity. The cavity is further dimensioned and arranged with respect to the transducer area to create, upon circulation of the tape in operation, sub-ambient pressure therein.

摘要： A drive-implemented method according to one embodiment includes guiding a magnetic medium over a magnetic head at an angle at which the magnetic medium flies over a leading outer portion of the head, engages a leading edge of a tape bearing surface of a central portion of the head, and engages an inner edge of a tape bearing surface of a trailing outer portion of the head. The inner edge of the tape bearing surface of the trailing outer portions skives air from the magnetic medium when the magnetic medium travels in a direction from the central portion towards the trailing outer portion.
