ABSTRACT:
By recording, reproducing and erasing information by using a recording thin film of the present invention, the information can be recorded, reproduced and erased by a single beam spot and new information can be rapidly rewritten while recorded information is erased. The irradiation beam is not limited to a light beam but it may be other energy beam such as electron beam or ion beam. The record medium is not limited to a disk but it may be tape or card and is applicable to a recording thin film other than the described thin film and to other methods.
By using the described recording thin film, a manufacturing process is simple and reproducible, the recording/reproducing characteristic is high and the information can be stably stored for an extended time period. The record also may be rewritten a number of times.
