PURPOSE:To improve the reliability of connection acknowledging signals and to prevent a magnetic bubble memory cassette device from malfunction by connecting connection acknowledging signal terminals to a magnetic bubble memory cassette and both the end parts of a holder storing said cassette. CONSTITUTION:The connection acknowledging terminals 61, 62 and 63, 64 connected to both the ends of the magnetic bubble memory cassette holder are earthed. When the magnetic bubble memory cassette is connected to the holder through terminals 71, 72 and 73, 74 on both the ends of the magnetic bubble memory cassette corresponding to the terminals 61, 62 and 63, 64, connection acknowledging signals are impressed to a control circuit in the magnetic bubble memory cassette through an OR circuit 10. Since the acknowledging terminals are formed on both the ends of the terminals, the reliability of the connection acknowledging signals is improved and the magnetic bubble memory cassette device is prevented from malfunction. |
