摘要： A variable width flat tape head for bi-directional contact recording and method for making the same has significant advantages over both traditional contoured tape heads and single width flat heads for contact recording applications. The variable width head and process disclosed herein allows for greater ease of manufacturing, efficient layout of the devices on thin film wafers and provides a significant cost reduction in the production of the head compared to traditionally contoured tape heads. In addition, the present invention reduces unnecessary surface area where the tape contacts the head, thus reducing tape wear and damage that is present in single width flat heads (where the tape is in contact uniformly across the tape width), thereby providing a concomitant improvement in tape wear and life. In addition, the head of the present invention is simpler and less costly to manufacture than comparable devices with distinct advantages to the magnetoresistive ("MR") read element stripe height control process, device alignment and assembly processes particularly with respect to traditionally contoured tape heads, which require more complex and expensive manufacturing operations to form the tape head profile.
摘要翻译：用于双向接触记录的可变宽度扁平带头及其制造方法相对于传统轮廓带头和用于接触记录应用的单宽扁平头具有显着优点。这里公开的可变宽度头部和工艺允许更大的制造容易性，薄膜晶片上的器件的有效布局，并且与传统的轮廓带头相比提供了头部生产的显着成本降低。此外，本发明减少了磁带与磁头接触的不必要的表面积，从而减少了单宽平头（磁带在磁带宽度上均匀地接触）中存在的磁带磨损和损坏，从而提供了同时的改进在磁带磨损和寿命。此外，本发明的头部与具有与磁阻（“MR”）读取元件条纹高度控制过程，装置对准和组装过程相比具有明显优点的可比设备更简单且成本更低，特别是相对于传统的轮廓带头，其需要更复杂和昂贵的制造操作以形成磁带头轮廓。
