Abstract
Information-bearing signals are stored using high-temperature superconducting materials. Type II semiconductors, such as materials in the perovskite class, are used for recording. A vortex of electrical current is induced in a layer of the super-conductive materials which causing a magnetic field extending from the axis of the vortex. One or more vortices can be used to record one bit of information. The induced magnetic field is sensed for reading the stored information.
