It is related to a head control method. The head control method controls a protruding flying height of a head in which an energization amount applied to a heater element in the head to thermally expands the head. The head control method includes a resistance-value measuring step of measuring a resistance value of the storage element, an energization-amount calculating step of calculating an energization amount applied to the heater element such that the resistance value measured in the resistance-value measuring step reaches a reference resistance value, and a heater control step of performing control to apply the energization amount calculated in the energization-amount calculating step to the heater element.
