摘要： A batch fabrication technique is described that increases the manufacturing efficiency of servo write heads and also improves servo pattern definition for fine features, while reducing tape and head wear. Multiple heads are fabricated as a batch from one or more ferrite wafers. A nominally flat, large wafer surface and a contour suitable for uniform photoresist application and planar photolithography permit fine servo pattern definition. A rounded leading edge on the head creates an air bearing to reduce wear of the tape and of the head. Moreover, any head wear occurs at the leading edge rather than in the region of the head where the servo pattern is formed. The servo write head may have a substantially planar head surface. A leading edge is disposed adjacent to the head surface such that the tape contacts the leading edge before passing over the head surface. The leading edge is rounded to form an air bearing between the head surface and the tape. A rounded trailing edge may be disposed adjacent to the head surface such that the tape passes over the trailing edge after passing over the head surface. The head may be formed from an upper ferrite wafer having a non-magnetic spacer. Non-magnetic material is photolithographically defined to produce gaps above the spacer. The non-magnetic material may be photoresist, semiconductor materials, glass, metal or the like. The material may even be removed later to leave air gaps. The non-magnetic material forms a region where the field loops out to intersect the passing tape, thereby transferring a magnetic pattern to tape. Additionally, a lower ferrite wafer may be mated to the upper ferrite wafer to complete a magnetic circuit around the gaps. The upper or lower ferrite wafer may have a channel through which an inductive winding passes. Multiple heads may be formed through batch processing of the upper and lower ferrite wafers.

摘要： A servo head for magnetic tape is provided. The head includes a substantial planar head surface. The head includes a leading edge that is disposed adjacent to the head surface such that the tape contacts the leading edge before passing over the head surface. The leading edge includes a rounded portion so as to form an air bearing between the head surface and the tape. The leading edge can include an abrupt change in slope at the leading edge. Alternatively, the leading edge can include a smooth transition.

摘要： A servo head having a substantially planar head surface and a leading rounded edge is disclosed with a technique of utilizing the disclosed servo head to write to tape passing over the planar head surface, the tape separate from the servo head by an air bearing. The rounded leading edge on the head creates the air bearing to reduce wear of the tape and of the head. Moreover, any head wear occurs at the leading edge rather than in the region of the head where the servo pattern is formed. The servo write head may have a substantially planar head surface. A leading edge is disposed adjacent to the head surface such that the tape contacts the leading edge before passing over the head surface. The leading edge is rounded to form the air bearing between the head surface and the tape. A rounded trailing edge may be disposed adjacent to the head surface such that the tape passes over the trailing edge after passing over the head surface.

摘要： A head design that reduces wear at the leading and trailing edges where the tape contacts the head while minimizing any adverse effects on the performance of the head. In one embodiment of the invention, a localized layer of wear resistant material is formed on the leading edge where the tape contacts the head before passing over the head recording surface. In a second embodiment, the leading edge is formed as wear resistant material embedded in the head structure adjacent to the recording surface. And, in a third embodiment, the leading edge is formed as a wear resistant material strip affixed to the side of the head structure. For each embodiment, the wear resistant material may also be applied in the manner described to the trailing edge where the tape may also contact the head after passing over the recording surface.

摘要： A magnetic head suspension assembly and method are designed to include a substantially inflexible support arm mounted at one end to an actuator motor in a data storage disk drive system. At the opposite end of the support arm is a gimbal. An air bearing slider having at least one read/write head is connected to the gimbal. The gimbal is adapted to accommodate pitch and roll motion and is compliant in the direction perpendicular to a surface of the data storage medium to be read. The gimbal is parallel-coupled with a load spring that is connected to the support arm to apply a load force. This arrangement improves the shock-resistance characteristics of the suspension assembly, since the support arm does not add to the inertial force caused by accelerations from shock events. In a preferred embodiment, the electrical connection to the read/write head is via electrical traces that are printed onto the support arm and gimbal. Traces are also formed on the gimbal springs to extend to a solder-reflow location at an interface to the slider.
