Abstract: PURPOSE:To read and store a pattern by storing the read pattern under a temperature control with a head part into a superconductive material body. CONSTITUTION:A current is applied to a heater part 5, the temperature of a superconductive material body 3 is raised, the superconductive condition of the superconductive material body 3 is quenched, and in such a condition, the pattern having magnetic characteristics is placed on the title device. By turning off the power source of the heater part 5, and returning the temperature of the superconductive material body 3 to the normal temperature, the superconductive material body 3 is made into the superconductive condition again, and then the current is generated through the superconductive material body 3 by means of a magnetic field from the pattern. In such a condition, even when the pattern is removed from the device, since the current is generated only through a mesh corresponding to the magnetic field from the pattern, the pattern can be stored. Further, by detecting it by means of a signal detecting part 2, displaying by a host computer is attained. Thus, the pattern can be not only read but also stored.
