Abstract

PURPOSE:To make bubble cassettes, differing in memory capacity, compatible with each other by building in each bubble cassette peripheral circuits such as a function driver, coil driver, sense amplifier, and selecting circuit. CONSTITUTION:In a bubble cassette 18, magnetic bubble memory devices 22 each connecting with a function driver 19, a coil driver 20 and a sense amplifier 21 are provided and a selecting circuit 23 operating by selecting one bubble device 22 is further provided. Then, each function driver 19 is connected to the function signal terminal 24 of a connector, eah coil driver 20 to the coil signal terminal 25, and each sense amplifier 21 to the sense timing terminal 26. Further, the function drivers 19, coil drivers 20 and sense amplifier 21 are connected to a power terminal 27, and the selecting circuit 23 to a selection signal terminal 28.
