ABSTRACT:
A storage device comprising a main magnetic field generator, a rotary magnetic field generator and a number of plates of magnetic material which are arranged transverse to the main magnetic field and in which magnetic domains can be formed and transported along a domain guide structure consisting of discrete element. The domain guide structure comprises a switching device incorporating diverging switches which are arranged according to four orientations which correspond to corresponding orientations of discrete elements of said domain guide structure. The domain guide structures comprise diverging switches which may be arranged to be shifted with respect to each other over one or more discrete elements of the domain guide structure in different plates, each plate having a specific rotary magnetic field sequence.
