Abstract

PURPOSE: To enable the discontinuation of the rotary magnetic field in a short time by providing the memory means to memorize the contents of both the minor and major address counters.
CONSTITUTION: Memory circuit 18 memorizes the contents of minor address counter 10 counting the bit number within the minor loop and the contents of major address counter 16 counting the bit number within the major loop respectively. In case the trouble such as the cut-off of the power supply occurs, the abnormal signal is given from power supply supervisory circuit 20 to memorize the contents of counters 10 and 16 into stop address memory circuit 18. As a result, the magnetic bubble can be stopped immediately. Thus the packing space of the power source and others can be reduced, also facilitating greatly the control at the restart time of operation.
