According to one embodiment, there is provided a head flying height control method for controlling a flying height of a magnetic head from a magnetic storage medium. The magnetic head includes an element portion and a heater that effects a change in a protrusion amount of the element portion due to thermal expansion accompanying heat generation. The head flying height control method includes: causing the element portion to protrude a maximum protrusion amount by increasing a heater power of the heater; first-reducing the heater power based on a relation between the protrusion amount and the heater power until the protrusion amount becomes a predetermined protrusion amount; and second-reducing, if a head-medium property is better than a target value after the first-reducing, the heater power based on a relation between the head-medium property and the heater power so that the head-medium property matches the target value.
