A storage device has a head that floats over a rotating storage medium. The storage device includes a measuring unit that measures the operating time and a head slider having a head element. The head element includes a reading element, a writing element and a heater, and a control unit that controls a protruding amount of the head element, by issuing an instruction causing an amount of power of a first predetermined value to be supplied to the heater until the amount of time measured by the measuring unit becomes a predetermined value. When the amount of time exceeds the predetermined value, the control unit cause an amount of power of a second predetermined value that is lower than the first predetermined value.
