Abstract
PURPOSE:To use an interference element instead of the coil and to pick up a micro magnetic flux by forming the gap of a thin film magnetic head with a superconductive substance having a Meissner effect and forming a superconductive quantum interference element between the upper part electrode and the lower part electrode to penetrate the interference element with a magnetic flux to occur between an upper and lower part electrode. CONSTITUTION:A superconductive gap 13 of a thin magnetic head is formed by a first superconductive substance having a Meissner effect and between upper and lower part electrodes 6 and 7, a superconductive quantum interference element SQUID 12 is formed. When a signal is reproduced by the magnetic tape 11, a magnetic tape 11 is adhered to the superconductive gap 13, travelled at a constant speed and in accordance with the signal recorded at a tape 11, a magnetic flux phi is generated. The magnetic flux phi passes through the connecting part of upper and lower part electrodes 4 and 5 and the signal is induced to an element SQUID 12 by the passed magnetic flux phi. By the superconductive substance of the Meissner effect of the gap 13, the magnetic flux phi is erased, the element SQUID 12 is used as a coil and a micro magnetic flux is picked up.
