摘要： In one embodiment, a tape movement constraint for a tape drive system, comprises a tiltable tape roller bearing having a roller barrel biased in a first position on a pivot axis, using magnetic attraction between a movable magnet and a return path structure of magnetically permeable material. The roller barrel is pivoted on the pivot axis by conducting current through a fixed coil to generate a magnetic field which is conducted by the return path structure to interact with the magnetic field of the magnet. At least a portion of any air bearing between the moving tape and the barrel surface is quenched using grooves formed in the barrel surface. Other embodiments are described and claimed.

摘要： In one embodiment, a tape read/write head supported by a lever is biased in a first position, using magnetic attraction between a magnet supported by the lever, and a return path structure of magnetically permeable material. In the illustrated embodiment, the magnet centers itself, in the absence of a coil generated magnetic field, in the middle of a gap of the magnetic return path structure. In one aspect, the mass of the read/write head and one side of the lever may be balanced by the mass of the magnet and the other side of the lever. The lever and hence the tape read/write head carried by the lever, may be pivoted by conducting current through a coil to generate a magnetic field which is conducted by the return path structure to interact with the magnetic field of the magnet. As a consequence, the lever pivots on a pivot axis as a function of the magnitude and direction of the current through the coil. The face of the magnet may be divided into portions of opposite magnetic polarity to facilitate a relatively pure torque to be developed substantially without a net force. Other embodiments are described and claimed.
摘要翻译：在一个实施例中，由杠杆支撑的磁带读/写磁头通过使用由杠杆支撑的磁体之间的磁吸引力和导磁材料的返回路径结构而被偏置在第一位置。在所示的实施例中，磁体在没有线圈产生的磁场的情况下自身中心位于磁返回路径结构的间隙的中间。在一个方面，读/写头的质量和杠杆的一侧可以由磁体的质量和杠杆的另一侧平衡。由杠杆承载的杆和因此的带读/写头可以通过传导电流通过线圈来枢转，以产生由返回路径结构传导以与磁体的磁场相互作用的磁场。因此，杠杆作为通过线圈的电流的大小和方向的作用在枢轴上枢转。磁体的表面可以被分成相反磁极的部分，以促进基本上没有净力显着地发展相对纯的扭矩。描述和要求保护其他实施例。
