摘要：
A magnetic head increases the magnetic field strength just below a write gap 14 and thereby improves the recording resolution of a medium. To do so, an upper magnetic pole 10 and a lower magnetic pole 12 are disposed facing one another with the write gap 14 in between, with an end surface of the lower magnetic pole 12 being I-shaped and an end surface of the upper magnetic pole being T-shaped due to the upper magnetic pole 10 being formed of a first upper magnetic pole 10a that is disposed facing the lower magnetic pole 12 and is formed in an I shape that is shorter than the lower magnetic pole 12 and a second upper magnetic pole 10b that is joined to the first upper magnetic pole 10a and is formed wider than the first upper magnetic pole 10a.
