In this invention, in a recording apparatus for forming a track of a disk-shape recording medium (41) capable of optical information reproduction, the recording apparatus comprises a deflection device (61) for deviating a recording beam from a light source in a radius direction of said disk-shape recording medium; and a deflection-control signal generating device (62-78). 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 said predetermined frequency. The superimposition of the second signal can be done while retaining the predetermined frequency. |
