Thin film magnetic head having a lower pole shaped to improve reproduction characteristics

摘要

The leading edge of a lower pole is constituted by a protruded central parallel portion, opposite end parallel portions, and slanted portions coupling the central parallel portion and the opposite end parallel portions. The width Twc of the central parallel portion is set to 10 to 25% of the total width Twa of the lower pole. The thickness P1' of the opposite end portion is set in the range from 3/1 or thicker to 3/2 or thinner than the thickness P1 of the central parallel portion.
