A disk apparatus includes (a) an actuator having a head supporting arm with a tab formed on the arm and a voice coil fixed to the arm, which arm is rotatable on a horizontal rotary shaft as well as on a vertical rotary shaft, (b) a voice coil motor having an upper yoke with a magnet fixed to the upper yoke and a lower yoke sandwiching and confronting the voice coil, and (c) a ramp section guiding and holding the tab at a refuge place. When the actuator at the refuge place starts loading with a starter command, a pulsed driving current is applied to the voice coil temporarily for urging the tab against a tab-holding plane of the ramp section, thereby making use of repulsion force generated on the actuator, so that the tab can leave the refuge place efficiently for carrying out the loading operation.
