Abstract
PURPOSE: To enable double track controlling, by placing two reading cores at a prescribed distance in a head for reading information from a servo-information surface.
CONSTITUTION: Both the reading cores A, B are placed at the distance of np+p/2 (p denotes the pitch of servo-tracks and n denotes an integer) in the servo-head so that the output wave from the core A is advanced by 1/2p ahead of that from the core B. Position control signal waves obtained from the output waves deviate by 1/2p from each other. The outputs from the cores A, B are alternately applied to a control circuit to enable the double track controlling.
