PURPOSE:To prevent extinction of magnetic bubble information stored and held in a nagnetic bubble memory device in a case, by providing an external magnetic shielding body on a part of a case of a magnetic bubble memory cassette. CONSTITUTION:A magnetic bubble memory cassette is incorporated with a magnetic bubble memory device 6 in a case 11 made of synthetic resin, and the side is provided with a connector 12 for connecting a magnetic bubble memory device. On the outside surface of the case 11, a permalloy plate 13 is provided as a magnetic shielding body. In this way, magnetic transmission into the case from an external magnetic field is dropped, and extinction of magnetic bubble information stored and held in the device is prevented. |
