Abstract

PURPOSE:To shorten an initializing time in case an electric power supply of a magnetic bubble memory element provided with a block replicator has been turned on, by executing a stop in case the electric power supply has been cut off and a transfer of a bubble in case the electric power supply has been turned on, by a specific method. CONSTITUTION:In case disconnection of an electric power supply has been detected when a magnetic bubble train is being transferred to a major part, it is stopped at only one of an even position or an odd position at all times among major positions countered by a major counter 5. Also, when the electric power supply is turned on, a magnetic bubble train of a minor loop by the first access is inserted into a space of the residual magnetic bubble train in the major part, and is transferred. For instance, between the major counter 5 and a driving controlling circuit 8, a stop position setting circuit 6 is provided, the present bit position is detected by a counting output of the major counter 5, a stop position of the magnetic bubble train is set so as to be outputted to the driving controlling circuit 8, and said stop is executed.
