    摘要: A head amplifier circuit supplies a writing current, having a direction in accordance with recording information, to a head for recording information on a recording medium. The head amplifier circuit includes a reference voltage generating portion for generating a reference voltage, a constant current generating portion for generating a constant current based on the reference voltage generated by the reference voltage generating portion, and a grounding portion. During one period of time, the constant current generating portion supplies the constant current to a first end of the head and the grounding portion grounds a second end of the head. During another period of time, the constant current generating portion supplies the constant current to the second end of the head and the grounding portion grounds the first end of the head.
