ABSTRACT:
A matrix to be used for fabricating disc shaped record carriers is produced by illuminating a photolacquer layer with a laser beam while the layer moves transverse to the beam axis and by controlling the beam so that it simultaneously produces a succession of spots modulated according to the information recorded and a continuous strip narrower than the spots and serving to provide a track guide for the scanning element of a playback device with which such a record carrier is to be used.
