Abstract
An information recording/reproducing apparatus is provided with a velocity control device for moving a recording and/or reproducing head from a current track to a target track under velocity control. A target velocity for the head is determined and the moving velocity of the head is detected by a detector. An instruction value for an actuator for moving the head is generated at every predetermined calculating interval on the basis of the target velocity and the detected velocity so that the head follows the target velocity. In the generation of the instruction value for the actuator for the head, the calculating interval can be switched into plural values by a switching device until the head reaches the target track.
