Abstract

Two erasable optical recording materials were evaluated for use in direct digital spot recording systems: a photodichroic from Corning and a photochromic from Plessey. The materials were tested in a static system to isolate the material parameters from the system characteristics. Both materials have potential for data storage applications. The photodichroic has the sensitivity, frequency response and noise characteristics for direct spot recording and has an amplitude readout mode. The photochromic has the necessary recording properties but requires a phase readout system. For both materials, the coating parameters must be optimized to meet the specific system requirements.
