Abstract
A holder in which a bubble cassette housing a bubble memory device is inserted. The contacts of the holder contact the contacts of the cassette when the cassette is inserted into the holder, so that current can flow into the bubble memory device. The holder contains a detector for detecting the insertion and withdrawal of the cassette. A circuit controls the current introduced into the magnetic-bubble memory device so that the current is introduced after the contacts of the cassette and the contacts of the holder are connected and is interrupted before the contacts of the cassette and the contacts of the holder are disconnected.
