<p>A magnetic bubble memory chip is disposed at a position surrounded by a rectangular annular core , having two pairs of opposits sides wound by a pair of wires, respectively, and is covered by a case for confining revolving magnetic field, thereby providing i revolving magnetic field to said chip.</p><p>I In a bubble memory, on the other hand, a per- mament magnet is used as a holding magnetic field source, lying at a predetermined angle to the chip. In the present invention, an inclination between the chip and the magnet is provided by forming projections on the revolving-magnetic-field confining case to be inserted between the chip and the magnet, or by having the case changed in plate thickness.</p> |
