摘要： Method and apparatus for guiding a moving tape having a tape edge parallel to a direction of motion of the tape wherein the tape is received tangentially on a curved surface having an edge. Force applied to the tape is increased as the tape drifts farther away from a nominal position so as to move the tape away from the edge of the surface. Lateral motion of the tape is dampened by breaking up an air-cushion between the tape and the curved 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 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.
摘要翻译： 描述了一种批量制造技术，其提高了伺服写入头的制造效率，并且还改善了精细特征的伺服模式定义，同时减少了磁带和磁头磨损。 多个头部从一个或多个铁氧体晶片制成批次。 标称平坦，大的晶片表面和适用于均匀光刻胶应用和平面光刻的轮廓允许精细的伺服模式定义。 头部圆角的前缘形成一个空气轴承，以减少磁带和磁头的磨损。 此外，任何头部磨损发生在前缘而不是在形成伺服图案的头部的区域中。 伺服写入头可以具有基本平坦的头表面。 前缘邻近头表面设置，使得带在通过头表面之前接触前缘。 前缘是圆形的，以在头表面和带之间形成空气轴承。 圆形的后缘可以邻近头部表面设置，使得带在经过头表面之后越过后缘。 头部可以由具有非磁性间隔物的上部铁氧体晶片形成。 非磁性材料被光刻定义以在间隔物上方产生间隙。 非磁性材料可以是光致抗蚀剂，半导体材料，玻璃，金属等。 材料甚至可以稍后移除以留下空隙。 非磁性材料形成区域，其中磁场循环出来以与通过的磁带相交，从而将磁性图案转印到磁带上。 此外，下部铁氧体晶片可以与上部铁氧体晶片配合，以在该间隙周围形成磁路。 上或下铁素体晶片可以具有感应绕组通过的通道。 可以通过上下铁素体晶片的批量处理形成多个头。
