Record Separator Patents (Class 360/130.1)
  • Patent number: 10679649
    Abstract: An apparatus according to one embodiment includes a module having a tape bearing surface, a first edge, and a second edge, where a tape tenting region extends from the first edge toward the second edge, the first edge being a first end of the tape tenting region, a second end of the tape tenting region being positioned between the first and second edges. The apparatus includes a guide positioned relative to the first edge for inducing tenting of a moving magnetic recording tape and a transducer positioned in the tape tenting region. In one approach, the transducer is a TMR sensor. In another approach, the tape bearing surface is planar. In yet another approach, the guide is positioned to create an inflection point of the moving magnetic recording tape at a location above the tape tenting region that is between the transducer and the second edge.

  • Patent number: 10418059
    Abstract: 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.

  • Patent number: 9870794
    Abstract: A magnetic tape device includes a magnetic tape as a storage medium; a travel unit that moves the magnetic tape along a travel route; a magnetic head that is arranged at the travel route and performs data reading and writing for the magnetic tape that moves on the travel route; and a lifter unit that is arranged at the travel route and contacts the magnetic tape which is stopped on the travel route, where the lifter unit is able to reciprocate in a direction that intersects the travel route so as to separate the magnetic tape from the magnetic head.

  • Patent number: 8027124
    Abstract: A system in one embodiment includes first and second modules, each module having a substrate, a closure, and a gap situated therebetween, the gap comprising transducers selected from readers and writers; wherein the closures face each other, wherein the closure and the substrate of each module form a flat tape bearing surface, wherein a module spacing is defined as a distance from a point proximate to the transducers in the gap of the first module to a point proximate to the transducers in the gap of the second module, wherein the module spacing is less than 1.3 mm and greater than 0 mm.
