PURPOSE:To stably operate a head regardless of temp., by changing the driving current value of the head corresponding to the temp. detection value of the head. CONSTITUTION:A means 1 for detecting the temp. of a head transmits the temp. of the head to a means 2 changing the driving current value of the head. The means 2 changing the driving current value of the head increases the driving current value when the transmitted temp. is low and reduces the same when high. Therefore, the head is stably operated regardless of the temp.
