Abstract

PURPOSE:To simplify the operation of a control circuit at writing by making the number of transfer bits from the bit just prior to a block replicate to a swap gate consist with that from a generator to the swap gate. CONSTITUTION:The page positions of minor loops 5, 5' at writing are decided on the basis of the information of a maker loop 15. When bubbles of writing page positions reach the positions 11, 11' of a replicator 12, generators 1, 2 start to operate. After completing a prescribed cycle, a swap gate 7 is actuated to execute writing operation. To execute the operation, the number of transfer bits from the bit just prior to minor loop to the swap gate must be made consist with that from the generator to the swap gate. Since the length of minor loops 5, 5' is limited, the number of bits is made consist through the turning constitution of minor loops.
