摘要：
A highly reliable magnetic head is provided where fluctuation in the form of the upper magnetic pole is prevented and recording density is improved. The magnetic head is equipped with a recording head where a lower tip magnetic pole and an upper tip magnetic pole are formed facing one another on both sides of a write gap and a coil is disposed on a rear side of the lower magnetic pole. The lower tip magnetic pole is provided with an apex part by forming the surface on the rear side on which the coil is disposed as an inclined surface, and an insulating layer that covers the coil is formed to the rear of the lower tip magnetic pole.
