ABSTRACT OF THE DISCLOSURE A cassette-type magnetic-bubble memory apparatus comprising a bubble cassette which houses a bubble memory device and a main apparatus which comprises a holder into which the cassette is inserted. The contacts of the holder contact the contacts of the cassette in cooperation with the action of inserting the cassette into the holder so that current flows into the bubble memory device. The main apparatus comprises a detectoring means for detecting the action of inserting and withdrawing the cassette. The circuit for controlling the current introduced into the magnetic-bubble memory device is constructed so that the current is introduced after the contacts of the cassette and the contacts of the holder are connected and is inter- rupted before the contacts of the cassette and the contacts of the holder are disconnected.
