Abstract
The invention comes within the field of digital memories having thin magnetic layers, for the propagation of domains. This memory is constituted by an anisotropic linear magnetic channel which is applied on a glass substrate and which has a single shift conductor in a Greek border configuration superimposed on it. Areas made of soft magnetic material are provided at the intersection between the channels and the conductors. According to such a structure, high-capacity shift registers which are of relatively rapid access (one shift step lasts about 500 nanoseconds) can be produced.
