Beschreibung
Zusammenfassung:	FM/6-18881/A Process for optically storing information A process for optically recording information on a recording material comprising a substrate coated with a layer of a dithioquinacridone, between which substrate and the dithioquinacridone layer or on said layer there may be provided a further layer of an organic hydrazone, or the dithioquinacridone layer is mixed with a hydrazone. The information is recorded by iradiation with laser light in the NIR range and can be read out once or repeatedly by measuring the shift in the absorption by the transmission or refection method. The system is an information carrier of WORM type.
