THIN-FILM MAGNETIC HEAD AND PRODUCTION THEREOF

PURPOSE:To approximate a gap depth to zero as far as possible by relatively retreating the front end of an insulating layer on both sides in the front end drawing part of a lower magnetic pole from the front end of the insulating layer on the front end drawing part of the lower magnetic pole.

description PURPOSE:To approximate a gap depth to zero as far as possible by relatively retreating the front end of an insulating layer on both sides in the front end drawing part of a lower magnetic pole from the front end of the insulating layer on the front end drawing part of the lower magnetic pole. CONSTITUTION:The magnetic head has the lower magnetic pole layer 7, the gap insulating layer 8, the lower insulating layer 10a, a coil layer 9, the upper insulating layer 10b and the upper magnetic pole layer 11 on a substrate. The front end a of the insulating layer n1 on both sides of the front end drawing part 7a of the lower magnetic pole 7 is retreated from the front end A of the insulating layer r2 on the front end drawing part 7a of the lower magnetic pole 7. Since the front end (a) is relatively retreated from the front end A in such a manner, the insulating layer r1 on both sides of the front end drawing part 7a is not exposed even if the gap depth is approximated to zero as far as possible. Then, the gap depth is approximated to zero as far as possible.
