Abstract
A device for reading information-representing magnetization patterns by means of a magneto-resistive element. The magneto-resistive element is in magnetic flux coupling with a plurality of magnetization patterns simultaneously. A desired portion of the element is selected for reading by influencing such portion by the external magnetic field of a magnetic bubble domain. Information positions can be read in sequence by moving the bubble domain along magneto-resistive element.
