发明名称 Apparatus and method for shielding magnetic heads during a sputtering operation
摘要 In the process for manufacturing the ferrite cores used in magnetic data transducer heads, a novel stacking of the bars from which the core pieces are cut allows these bars to mutually shield each other's back gap areas during the alumina sputtering step which sets the lengths of the read/write flux gaps. An inexpensive fixture supports the bars in the desired position during the sputtering operation.
