Abstract
PURPOSE: To make it possible to record hysteresis information effectively by inhibiting new write operation in an interval from when the memory capacity of a memory unit exceeds a fixed value until the next detection operation and while an error signal is supplied.
CONSTITUTION: When hysteresis information outputted from logic circuit 1 is stored in hysteresis storage unit 2, input register 10 detects 16 whether this hysteresis information is predetermined information. On the detection of circuit 16, storage control circuit 18 starts writing to memory unit 12 and inhibits new writing to unit 12 in an interval from when the memory capacity of unit 12 exceeds a fixed value until the next detection of circuit 16. Further, while an error signal is supplied from unit 1, new writing operation based upon the detection of circuit 16 is inhibited. Consequently, the hysteresis information can effectively be recorded without lowering the recording density as to the supply of the hysteresis information before the error occurrence of unit 1.
