Abstract

PURPOSE: To weaken the intensity of the leak magnetic field as less as possible by forming a pair of magnetic poles so that the leak magnetic pole may be in the circumferential direction of the magnetic disk.
CONSTITUTION: The plane form of magnetic pole 8 is made nearly semicircular so that the direction of leak magnetic field of pole 8 may coincide with the circumference direction of magnetic disk 9. At the same time, the magnetic pole space to cause orientation magnetic field 10 is set smaller than that to cause leak magnetic field 11. As a result, no effect due to the direction of field 11 is caused, and also the size of field 11 can be made smaller enough than that of field 10. Thus the intensity can be weakened sufficiently for the leak magnetic field.
