Summary:An apparatus for controlling a head loading of a disk drive and a controlling method therefor are provided to control a head to be loaded on a disk while a vertical displacement of the disk is far away from a parking position of the read/write head, thereby reducing collisions between the head and the disk. A displacement measurer measures a vertical displacement of a disk(120). A rotational angle detector detects a rotational angle of a spindle motor(122). A controller(151) controls a rotation of an actuator(130) according to the rotational angle of the spindle motor(122) and the vertical displacement of the disk(120). The displacement measurer measures the vertical displacement of an edge of the disk(120) by an RRO(Repeatable Runout) repeated at certain intervals according to the rotation of the disk(120). The displacement measurer includes a displacement measuring sensor(152).
