PURPOSE:To improve the compatibility of a bubble memory cassette, by connecting a shunting circuit for current adjustment between a main body side which has a pulse current driving circuit, etc., and a bubble memory cassette side which has a bubble memory chip, etc. CONSTITUTION:A device body 1 is provided with a pulse current driving circuit 2 with large capacity, etc., and a magnetic bubble memory cassette 3 is provided with a magnetic bubble memory chip 4, etc. Then, the main body 1 and cassette 3 are connected mutually through a shunting circuit 6 for current adjustment provided to the cassette 3. For this purpose, the variable resistance 6a of the shunting circuit 6 is adjuted to supply only a current required for the memory chip 4 to a conductor loop 5 from the circuit 2, so that while the compatibility of the cassette 3 is improved, the capacity of the memory chip 4 is increased. |
