Abstract
PURPOSE:To enable the initial writing of high accuracy with a simple structure by making a tracking servoestate by scanning the track already formed by a recording/reproducing head by the head for position detection and forming an adjacent track with the discrimination signal output obtd. from the position detecting head as the reference in timing. CONSTITUTION:The discrimination signal reproducing output obtd. to a position detecting head 3a by scanning the track 12 on which a servo zone is already formed is fed to a discrimination signal detecting circuit 8, a timing signal is formed and simultaneously with this timing signal the discrimination signal and burst signal in the specified frequency are written in the specified zones 13, 14 of the adjacent track. On the disk face, therefore, the track 12' on which a servozone is arranged in the form of correctly conforming to the diameter direction of a magnetic disk 11 is formed. The writing timing between tracks each other can be conformed without using the exclusive head for clock signal reproduction and the initial writing of a servo information can thus be executed with good synchronous accuracy and simple structure.
