ABSTRACT:
Recording apparatus for forming a track on a disk-shaped recording medium capable of optical information reproduction, comprises a deflection device for deviating a recording beam from a light source in a radial direction of the disk-shape recording medium and a deflection-control signal generating device. The deflection control signal is developed from the superimposition of a first signal having a predetermined frequency and a second signal having a lower frequency than the predetermined frequency. The superimposition of the second signal can be done while retaining the predetermined frequency.
