Abstract: In one general embodiment, an apparatus includes at least two modules, each of the modules having an array of transducers, wherein the at least two modules are fixed relative to each other, wherein an axis of each array is defined between opposite ends thereof, wherein the axes of the arrays are oriented about parallel to each other, wherein the array of a first of the modules is offset from the array of a second of the modules in a first direction parallel to the axis of the array of the second module such that the transducers of the first module are about aligned with the transducers of the second module in an intended direction of tape travel thereacross; and a mechanism for orienting the modules about an axis orthogonal to the plane in which the arrays reside to control a transducer pitch presented to a tape.

Abstract: PROBLEM TO BE SOLVED: To enhance a yield per wafer by using a thinner blade and reduce a rate of an error caused by the excursion of the blade in sawing, on dicing a membrane wafer.
SOLUTION: A closure is joined to a section of the thin-film wafer. A string is sliced from the section of the wafer by the blade, wherein the closure and the thin-film wafer are through-sliced in a way that the reverse side of the blade engages with an equal surface area of the closure.

Abstract: Bei einer allgemeinen Ausführungsform beinhaltet eine Vorrichtung zumindest zwei Module, wobei jedes der Module ein Array von Wandlern aufweist, wobei die zumindest zwei Module im Verhältnis zueinander feststehend sind, wobei eine Achse jedes Arrays zwischen gegenüberliegenden Enden davon definiert ist, wobei die Achsen der Arrays ungefähr parallel zueinander orientiert sind, wobei das Array eines ersten der Module von dem Array eines zweiten der Module in einer ersten Richtung parallel zu der Achse des Arrays des zweiten Moduls so versetzt ist, dass die Wandler des ersten Moduls ungefähr mit den Wandlern des zweiten Moduls in einer beabsichtigten Richtung eines Bandlaufs darüber ausgerichtet sind; und einen Mechanismus zum Orientieren der Module um eine Achse orthogonal zu der Ebene, in der sich die Arrays befinden, zum Steuern eines Wandlerabstands, mit dem ein Band konfrontiert wird.

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.
