ABSTRACT:
The use of a photoconducting material having specific characteristics in conjunction with a heat sensitive optical recording medium also having specific characteristics yields desirable properties. Specifically, through the use of this combination an optical recording medium that has a relatively low applied power threshold for writing and yet a relatively long-term stability is obtained. The photoconductor material should have an unilluminated resistivity of at least 10.sup.6 Ohm-cm and should undergo a resistivity descrease of at least 10.sup.5 upon illumination to yield this desired attribute.
