Abstract
A method and apparatus for operating a data recording medium reproducing device in which a pick-up device reads address data from a recording medium such as a video disc. The read off data is compared with a supply desired address data to form a signal which represents whether the present position is inside, outside, or coincident with the desired position. A sequence controller operates in response to the output of the comparison to drive coarse and fine adjustment devices which position the pick-up device successively until the desired position or a position within the vicinity of desired position is reached.
