摘要：
Magnetic head comprising two magnetic circuits (1, 1') attached to each other. Two parts (14, 14') made of non-magnetic material are located beneath the gap of the head. The magnetic poles 3, 3' are made with thin layers on the magnetic circuits (1, 1') and the parts made of non-magnetic material. The material for bonding the magnetic circuits sets up the gap (5) between the poles (3, 3').
