ABSTRACT
A thermoplastic/absorbent double layer type optical memory was developed. The thermoplastic was monodispersed polystyrene of which the molecular weight was 800–110 000, and the absorbent was Cu phthalocyanine. The erasing properties were dependent on the molecular weight. The medium was best when the molecular weight was 2000 and the record/erase repetition could be more than 350. The dye addition to the polystyrene increased the recording sensitivity but decreased the maximum limit of record/erase repetition, so the dye content was preferable to be less than 10 wt. %.
