ABSTRACT:
In order to eliminate a crosstalk component of the reproduction signal and to provide a high level of recording density, a method for recording an information signal having a synchronizing signal on a recording disc comprises a first step for forming a first portion of recording tracks in which information signal is recorded on the recording disc rotated at a constant angular velocity of rotation so that positions of the recording tracks in which the synchronizing signal is recorded are aligned in radial directions of the recording disc, and a second step for forming second portions of recording tracks in which the information signal is recorded on the recording disc under a condition that the angular velocity of the rotation thereof is varying, wherein the first and second portions of the recording tracks are formed alternately.
