PURPOSE: A heat support magnetic recording system is provided to heat a magnetic recording medium by arranging laser predistortion with magnetic predistortion. CONSTITUTION: A signal generator generates a trigger pulse signal by using a clock signal (210). A variable delay element (246) controls alignment between a laser trigger pulse signal and a magnet write signal. A phase difference detector (262) controls the variable delay element. A trigger-available pulse generator circuit generates a laser pulse control signal based on the trigger pulse signal. A magnetic write head records data in a magnetic storage medium. A laser diode (242) heats the magnetic storage medium.
