A head positioning apparatus capable of positioning a head at high speed and with high accuracy is provided. The head positioning apparatus includes a magnetic head, a head supporting mechanism, a coarse actuator, a fine actuator, a head position detection part, a fine movement control system for controlling the fine actuator based on the head position detected by the head position detection part, a head moving distance estimation part estimating the head moving distance representing the distance the magnetic head moves, and the coarse movement control system for controlling the coarse actuator based on the head moving distance estimated by the head moving distance estimation part.
