Abstract

PURPOSE:To prevent the destruction of information, by always stopping the rotary magnetic field of a cassette type magnetic bubble memory in the prescribed direction with the operation of a switch which is caused by opening a cover. CONSTITUTION:When a cover 17 is closed, a control circuit 20 can drive a cassette type magnetic bubble memory device 1 via a coil driver 21. When the cover 17 is opened, a switch 19 works. Thus the operation stop signal is supplied to stop the bubble driving. Accordingly the cover 17 is always opened when the device 1 is taken out of a holder 15 and after the bubble driving is stopped. As a result, the destruction of information can be prevented.
