An apparatus, system, and method are disclosed for dynamically controlling a recording head substrate bias voltage. The apparatus includes a midpoint module and a substrate module. The midpoint module calculates a midpoint voltage of a plurality of data read elements and servo read elements contained in the head. The substrate module calculates a substrate bias voltage. The apparatus, system, and method dynamically control the substrate bias voltage post-assembly, minimizing certain head degradations and extending the life of associated head readers.
摘要:
A tape recording head is provided comprising a support plate having a contoured surface with an opening in the contoured surface which allows head chips to protrude far enough to allow proper head tape contact for recording. The support plate is fixed on a coarse actuator so that the support plate and coarse actuator move together perpendicular to the motion of the recording tape. The head chips comprising rowbar substrates containing a multiplicity of recording elements are supported on a carrier mounted on a fine actuator and are not fixed to the support plate to allow low mass fine actuation.

A tape guide assembly and tape drive system including the same comprise a roller guide adapted for engaging a tape wrapped around at least a portion of an outer surface thereof, and at least one support for lifting the tape from the roller guide.
摘要:
A magnetic head includes a wafer substrate and a conductive underlayer formed directly on the substrate. An insulating layer is formed above the conductive layer. A reader and/or writer thereof is formed above the insulating layer. Another magnetic head includes a substrate and an insulating underlayer formed above the substrate. A conductive underlayer is formed above the insulating underlayer. An insulating layer is formed above the conductive underlayer. At least one device is formed above the insulating layer, the at least one device being selected from a group consisting of readers, writers, and combinations thereof. Tape drive systems and methods for forming such heads are also presented.
摘要:
A method is provided for providing air-skiving edges of a tape head. A slot is created in an upper face of a substrate of a tape head. The slot includes at least one edge defining an edge of a tape bearing surface (TBS) of the tape head. The surface of the tape head is then formed and finished, such as by lapping. A grind operation is subsequently conducted to form a notch in the upper face of the substrate of the tape head. Such notch extends from the slot to an outside end of the substrate of the tape head.
