Abstract
PURPOSE:To shut off external noise and to obtain a high signal to noise ratio by providing a magnetism sensing part between the fine gap of a hermetic box consisting of a superconductor and a magnetic flux passing gap thereof and disposing the fine gap in contact with or proximity to the surface of a magnetic recording medium. CONSTITUTION:The hermetic box 3 is constituted of a superconducting material. The fine gap 4 is provided to a part of the box 3 and another magnetic flux pass gap 5 is provided to the position here the magnetic flux passes through the gap 4. A magnetic sensor 1 having an electrode such as magneto-resistance effect element. Hall element and SQUID consisting of Fe-Ni, Ni-Co alloy, etc., is disposed to the position where the signal magnetic flux entering from the gas 4 is sensed. The gap 4 is then brought into contact with or proximity to the surface of the magnetic recording medium 7, by which the signal magnetization is detected. Since the magnetic head can be shut off from the outside world by the hermetic box consisting of the superconductor, the high signal to noise ratio is obtd.
