Abstract

PURPOSE:To prevent recorded contents from being damaged due to the influence of an external magnetic field at the time of storage by surrounding a magnetic recording medium by a superconductor, and only at the time of magnetic recording and reading, breaking the critical state of the superconductor to execute magnetic recording and reading. CONSTITUTION:The magnetic recording medium 2 on a substrate 1 is surrounded by the superconductor 3. A heater 6 heats the superconductor 3 arranged just under the heater 6 to break the superconductive state of the part. Under said state, an electric signal is applied to a coil 5 to generate magnetic flux on a magnetic head 4. The superconductor 3 in the superconductive state shows complete reverse magnetism and magnetic flux interrupted from being entered the superconductor 3 can be allowed to execute magnetic recording on a part 8 by breaking a partial superconductive state by heating and forming a normal conductive state. On the other hand, the contents already magnetically recorded on the part 8 can be read out from the head 4. Since the medium 2 is surrounded by the superconductor 3 in this method, the recorded contents can be prevented from being magnetically damaged by the external magnetic field.
