ABSTRACT:
A magnetic bubble memory herein includes a detection circuit which responds to changes in data signal which occur in consecutive detection intervals. In one embodiment changes from both 0 to 1 and from 1 to 0 are used. Improved operating margins result. Correlated coding techniques are shown to preclude propagation of errors.
