Abstract: PROBLEM TO BE SOLVED: To provide an improved driver circuit for a writing head of a disk storage device. SOLUTION: In this circuit, the current is supplied to one terminal of the writing head in the manner of activating a pull-up device of one driver sub- circuit by a control circuit, meanwhile, the current is absorbed from another terminal of the writing head by activating a 1st current sync circuit of another driver sub-circuit.
