Title: Thin film magnetic head
Inventor: NANAUMI SACHIKO
IPC: G11B5/31
Filed: 1985-11-06
Abstract: PURPOSE:To regulate the gap depth with high accuracy by gradually increasing the core width of either of a lower magnetic core and an upper magnetic core up to a position where a desired gap depth is obtained in the gap depth direction from a tape slide face. CONSTITUTION:The 1st magnetic core 2 is increased gradually in the direction of magnetic gap depth (gd) and the gap depth (gd) is detected by measuring the core width TW2 of the 1st magnetic core. The track width of the magnetic head depends on the core width TW1 of the 2nd magnetic core and the width TW1 is constant in the direction of the gap. Further, the core width is reduced near the sliding face and the relation of TW1<TW2 exists, then the magnetic flux is reduced near the gap and the reducing effect is obtained. Since the magnetic head pattern itself controls the gap, the accuracy of gap is improved without being affected by the deviation between the polishment progressing direction and the parallelism of the magnetic head pattern and by the shape of curved face of polishment.
