As a result, a disk can be obtained which has inside coercive force higher than outside one as shown by the graph. In this way, the O/W characteristic of the γFe 2 O 3  film with a write current of 70mA is shown by the figure.

Abstract: PURPOSE:To perform fast repetitive arithmetic even for many data like a fuzzy set by providing a loop processing circuit which counts a loop frequency supplied from outside. CONSTITUTION:A loop frequency included in an instruction when supplied to the loop processing circuit 3 is decoded by a decoder 31 and loaded in a loop counter 32.

At the end point of the loop processing, the control circuit 2 checks the value in the loop counter 32 and judges whether or not arithmetic is repeated at the given loop frequency. When the frequency is not reached, an increment signal is sent to the loop counter 32 to increase its value by one and the arithmetic is put back to the state held in the state holding circuit 4, but when the arithmetic is done at the given loop frequency, an advance to next arithmetic control is made.
