Title: Magnetic head
Inventor: TAKAGAKI ATSUSUKE
IPC: G11B5/235
Filed: 1987-10-16
Abstract: PURPOSE:To suppress flux leakage to a gap from being generated in a magnetic head and to increase a write magnetic field by forming a gap forming material by a superconductive thin film. CONSTITUTION:A gap part is constituted of a lower pole part 1, an upper pole part 2, an insulator 5, and the superconductive thin film 9 used as a gap forming material. The permeability of a superconductor is set at zero effectively by its Meissner effect. In other words, since magnetic resistance becomes infinite, the magnetic flux passing the upper and the lower pole parts is prevented from passing the inside of the superconductor that is the gap forming material, and all of them are pushed out outside the gap part. In such a way, the write magnetic field on a recording medium can be intensified.
