A method and apparatus for controlling an access mechanism within a disk drive are disclosed. A servo apparatus comprises a first detection module for discretely detecting a displacement value of an access mechanism from a target position at predetermined time intervals, a first feedback module for calculating a first feedback value on the basis of the detected displacement value, a second detection module for discretely detecting a physical value, including the speed of the access mechanism, at least once at each of the predetermined time intervals, a second feedback module for calculating a second feedback value on the basis of the physical value, including the speed, and a motor driving module for driving a motor according to the first feedback value and the second feedback value.
