Summary:According to one embodiment, a magnetic recording and reading apparatus has a magnetic head and a system controlling a flying height of the magnetic head. The system includes a main control unit, a resistance measurement unit which measures a resistance value of a magnetic flux control layer, a calculation unit which obtains a resistance value change rate with respect to an initial resistance value, a determination unit which determines a flying height for recording corresponding to the resistance value change rate, and a flying height control unit which controls a flying height of the magnetic head.
