    Abstract: A media abrasivity testing system includes a carrier 402 for receiving a module 204, a transport mechanism 404 for running a tape 406 across a tape bearing surface 209 of the module, and a measuring device 412 for measuring an extent of wear of a coating on a tape bearing surface of the module. The coating may be transparent and the measuring device may be an ellipsometer or a stylus profiler. The module can include a body having a tape bearing surface, the body having an approximate tape bearing surface profile and dimensions as a module of interest. The module may be an operative module for a tape head or can be a nonfunctional dummy. A method of testing can include measuring an initial coating thickness on a tape bearing surface of a module in a carrier, running a tape across the tape bearing surface, and at intervals, measuring a residual thickness of the coating.

    Abstract: A magnetic head assembly with an air bearing surface (ABS) layer over a double-shielded magnetoresistive (MR) sensor and a write gap formed between two spaced magnetic pole tips, with an optional write-gap shield disposed so that one magnetic pole tip is disposed between the write-gap shield and the other magnetic pole tip. At least one of the MR element shields is electrically connected to one of the MR signal lead conductors (preferably the one having the most positive potential) and the one magnetic pole tip (and/or the optional write-gap shield) is coupled to the clamped MR element shield with an electrical conductor. For multi-track read/write arrays, the connection between adjacent reader shield and writer pole and/or shield is provided independently for each read/write pair in the array, thereby equalizing the voltage environments to reduce variations in the chemical/mechanical erosion of the read and write head ABS layers.

    Abstract: A tape movement constraint is provided for a tape drive system which moves a tape longitudinally along a tape path across a tape head, the tape having longitudinal tracks. The tape head has a track following servo system for moving the head laterally for following lateral movement of the tracks, where the tape is subject to lateral transient movement. A tape roller bearing closely adjacent the tape head is rotatable about a central axis parallel to the cylindrical peripheral surface, allowing the tape freedom of movement in the longitudinal direction. The tape roller bearing has a frictional cylindrical peripheral surface for contacting and engaging the surface of the tape and constraining movement of the tape in the lateral direction, thereby reducing the rate of the lateral transient movement of the tape to allow the track following servo system to follow the reduced rate lateral transient movement of the longitudinal tracks. Any potential air bearing that could form between the surface of the tape and the surface of the roller bearing is collapsed to insure that the roller bearing frictionally contacts and engages the surface of the tape.
