摘要： A batch fabricated multi-element head is made from interlocking ferrite parts to form a low contoured surface for interfacing with a magnetic medium, such as a flexible disk. On another surface, a multi-turn conductive coil is formed by thin film process and cooperates with a flux path bar to define the magnetic flux field.

摘要： A method for batch fabricating magnetic heads with a desired cant angle in the transducing surface of the magnetic core. The cant angle reduces the "Minor Bit" phenomenon. The two parts of the core which require the cant angle are mounted on a fixture so that a grind wheel is simultaneously in contact with both parts. Materials are simultaneously subtracted (i.e., grind away) from both parts to create mirror images at the surfaces which adjoin the grind wheel. The surfaces are then cleaned and glassed to provide a core bar with intimate fit. The core bar is diced into individual cores and is lapped to size. The individual cores are then fitted into a slider assembly to form the magnetic head.
摘要翻译：一种用于在磁芯的转换表面中批量制造具有所需倾斜角的磁头的方法。倾斜角度减小了“次要位”现象。需要倾斜角度的芯部的两个部分安装在固定装置上，使得研磨轮同时与两个部分接触。同时从两个部分减去（即磨掉）材料，以在与研磨轮相邻的表面上产生镜像。然后将表面进行清洁和玻璃化，以提供牢固配合的芯棒。核心棒被切成单独的核心并且被大小调整。然后将各个芯件装配到滑块组件中以形成磁头。

摘要： A head is moved toward and rotated against an abrasive while its resistance is monitored by a four-lead bridge. Prior to final manufacture, the head includes a highly conductive segment which surrounds the active head element on three sides and is electrically connected to it at one point. The segment is ground away during manufacture. Two leads from the head are connected to two slip rings, and each slip ring has two pairs of brushes, each wire from the bridge going to a different brush pair. Head movement toward the abrasive is terminated when a predetermined head resistance is detected by the bridge.
摘要翻译：头部被移动并旋转抵靠研磨剂，同时其电阻由四引线桥监测。在最终制造之前，头部包括高度导电的部分，其在三个侧面上围绕有源头部元件，并且在一个点处电连接到该部分。在制造过程中，该部分被切掉。来自头部的两根导线连接到两个滑环，每个滑环具有两对刷子，每根电线从桥接到不同的刷子对。当通过桥梁检测到预定的头部电阻时，朝向磨料的头部移动终止。

摘要： An AC magnetic erase head having improved AC erase characteristics, the magnetic head being formed of two half core elements of a magnetic material, preferably ferrite, defining an irregular edged or jagged-edged gap, and including a non-magnetic substance, preferably glass, within the gap. The magnetic head is preferably produced by thermally etching ferrite magnetic material forming the half core elements by means of relatively prolonged heat soak at an elevated temperature.
