Abstract
PURPOSE: To simplfy and ensure the tracking adjustment by providing a servo- track for the tracking adjustment in the outer peripheral region of the data track of a disc.
CONSTITUTION: A servo-track 8, which is separated from a data track 7, is provided in the outer peripheral region of the track 7 which is formed in a disc 1. If the servo-head is moved forward to the position of the track 8 so that the data head is shifted in accordance with the reading waveformes by the data head at that time, then the tracking adjustment of the disc 1 can be simplified and ensured
