PURPOSE:To increase the general-purpose properties of a magnetic buble memory device using a cassette type bubble memory, by providing a means which can transfer the signal showing the capacity between the cassette type bubble memory and the magnetic bubble memory device. CONSTITUTION:The specific terminals A0, A1 and A2 are designated for transmission of the signal of capacity among the connector terminal groups 15 and 16 of the main body of a memory device 13 and a cassette type bubble memory 14. The voltage is applied to terminals A0-A2 of the device 13 and then connected to a controller via NOT circuits 17-19. The signal generated from the device 13 by the connecting method of the terminals of a cassette to the controller is set to correspond to the capacity of the device 13. As a result, the capacity of the memory 14 can easily known. This increases the general-purpose properties of a magnetic bubble memory element. |
