Abstract Vacuum sublimed thin films of the blue dye hydrogen phthalocyanine (H2Pc) were incorporated into various optical recording structures. The dye was shown to be thermally, hydrolytically, and oxidatively stable. In all cases, the writing mechanisms are dependent on the sublimation of H2Pc. Several recording structures which take advantage of the sublimation property of H2Pc are demonstrated, including pit forming and bubble forming media. These H2Pc-based optical recording structures show very high optical contrast and low writing threshold energies. In addition, very thin films (50–75Å) of H2Pc were incorporated into a tellurium-based medium, which significantly enhanced the writing contrast observed in that medium.
