Abstract
A reversible optical recording medium is comprised of an electrically conductive layer overlain by a thermoplastic layer containing a light absorptive compound selected from the group consisting of metal complexes of substituted ethylene dithiols having the structure ##STR1## where M is Pt, Pd, or Ni and R and R' are independently alkyl, phenyl or substituted phenyl groups. Information is recorded by sequentially charging the recording medium and then heating it above its softening temperature by absorption of the recording light beam in the thermoplastic layer.
