Abstract
A magnetic head has a lower sub-magnetic pole and an upper sub-magnetic pole disposed to be adjacent to a moving magnetic disk. The lower sub-magnetic pole and the upper sub-magnetic pole are placed adjacent one another with a predetermined interval at an adjacent point to the magnetic disk. A magnetic field is generated between those magnetic poles so that the magnetic disk is magnetized. A soft magnetic film extending between the magnetic poles and a first non-magnetic film and a second non-magnetic film supporting the soft magnetic film are disposed between the magnetic poles.
