Optical and electrical methods of information recording on chalcogenide glassy semiconductors are compared. It is shown that techniques based on a reversible glass-crystal phase transition are similar for the optical and electrical cases and the main mechanism of phase transition is determined by thermal heating. It is supposed that the known advantages of optical and electrical information recording by short pulses are possibly related to the existence of a wide power range of pulses recording without damage, compared with the appreciably narrower range at longer pulse durations.
