ABSTRACT:
In erasable magneto-optical storage layers an improvement of the signal-to-noise ratio during reading is achieved, in that during recording the laser pulse is resolved into a sequence of short pulses, the pulse spacings between the individual pulses being suitably equal to the pulse duration.
