摘要：
A recording medium is disclosed, which comprises as the main component an amorphous lead oxide or a lead oxide at the metastable state, having the formula PbL X M Y O z ' wherein L is Fe, Co or Ni and M is Nb or Ta. The recording mediums are drastically changed in their electrical and optical properties by application of heat, due to the characteristics inherent in the main component, and such changes make the recording medium highly useful for recording by laser light or heat.
