Abstract

We on high density recording experiments of erasable digital information in magneto-optical amorphous layers on pregrooved discs. The recording and reading of informa-tion is done on a recorder provided with an AlGaAs laser and equipped for polarization-sen-sitive read-out of the Kerr effect. The signal-to-noise ratio and the bit error rate of the recorded information have proved to be sufficient for an information density up to 0.4 Mbit/mm².
