Abstract
PURPOSE:To enable the reading out with the same device as for superconductive magnetic disks by constituting the titled disk ROM of a disk-shaped substrate and thin high-temp. superconductive ceramics film bored with holes intermittently with recording binary information data and applying magnetic field onto this thin ceramics film so that permanent current is stored around the holes. CONSTITUTION:This disk ROM consists of the disk-shaped substrate 1 and the thin high-temp. superconductive ceramics film 2 coated and formed on the surface thereof. The holes 4 corresponding to the recording binary information data are bored in the thin high-temp. superconductive ceramics film 2. The recording binary information data is maintained by applying the magnetic fluxes to the holes 4. The magnetic fields are, therefore, penetrated only in the parts having the holes 4 and the eddy current I which is the permanent current exceeding the critical magnetic field Hc flows when the external magnetic fields He are applied thereto from above. The reading out of the written information by detecting the eddy current I is thereby enabled at the time of reading out.
