Abstract

PURPOSE: To reduce the number of components for the in-surface magnetic field drive and to make small the unit, by connecting two diodes common to a plurality of drive coils, between the grounded power supply terminal and a plurality of switch terminals.
CONSTITUTION: The drive coils 30 and 31 give the in-surface magnetic field to the magnetic bubbles, and the diodes D11 and D31 are connected to the first power supply terminal 34. Further, the switches S21,S22,S41 and S42 are connected to each terminal of the coils 30 and 31 and the second (grounded) power supply terminal 35, and the switches S1 and S3 are connected to the terminal 34 for one terminal and other terminal is connected to the coils 30 and 31. diodes D51,D52,D61,D62 are connected to other terminal of the switches S1 and S3, and common diodes D2 and D3 to the coils 30 and 31 are connected from the terminal 35 to other terminal. Thus, the number of components required for in-surface magnetic field drive is decreased and the unit can be made small in size.
