ABSTRACT:
A magnetic bubble memory chip is disposed at a position surrounded by a rectangular annular core having two pairs of opposite sides wound by a pair of wires, respectively, and is covered by a case for confining revolving magnetic field, thereby providing a revolving magnetic field to said chip. A bubble memory includes a permament magnet used as a holding magnetic field source, lying at a predetermined angle to the chip. An inclination between the chip and the magnet is provided on the revolving-magnetic-field confining case to be inserted between the chip and the magnet by having the case changed in plate thickness.
