摘要：
According to one embodiment, a magnetic head having a head slider which holds a magnetic head unit including a heat-generating element for controlling the flying-height and a high-frequency oscillator for performing high-frequency assisted writing, and on which terminals connected to the magnetic head elements are used in the smallest number required. Terminals are mounted on the head slider and are connected to the magnetic head unit. The terminals include at least one current-supplying terminal that is connected to the heat-generating element serving to control the flying height and to the high-frequency oscillator.
