Device for close-packed magnetic domains |
摘要 |
A device for storing digital information in the form of magnetic domains including at least two ferrimagnetic layers on a substrate. The ferrimagnetic layers are separated by a compensation wall and in the presence of a bias magnetic field single magnetic domains and superposed magnetic domain pairs, the superposed domains being separated by a compensation wall, are generated. All single and superposed domains are mutually repulsive. The domains within a superposed pair are attracted to each other. The generated domains are propagated to a shift register and when the reigster is filled a row of domains is coincidentally propagated, transversely out of the register, to a domain array region adjacent the register. Rows are then propagated through the array region to a second shift register where they are individually detected and annihilated. A control device assures the proper working relationship between all elements.
