摘要： Upon correction, a preheat sector number measurement unit measures a preheat sector number which corresponds to transition time from when electric power distribution to and heating of the heater by preheat electric power is started until when it is stabilized to a predetermined target flying height. Upon reproduction or recording, a flying height control unit distributes electric power to the heater from a sector position which is before a target sector by the preheat sector number so as to perform preliminary heating, and then controls the flying height of the head to a predetermined target flying height from a target sector position.
