Paper Abstract

The optical recording characteristics of a silver halide thin film structure were investigated with respect to its possible use as a read-write-erasable medium. Tracks of ~1μm spots were recorded using a polarized He-Ne as the writing source. The recorded tracks were viewed with a GaAs laser between crossed polarizers; the writing energy density was determined to be ~0.2 joules/cm2 in the transmission mode. Erasure was also demonstrated by re-exposing a portion of the recorded tracks with the defocused write laser with its polarization rotates by 45° from the original write polarization direction.
