摘要
An information medium capable of recording the information at a high density in a convenient manner is provided. Also provided is a method capable of readily reproducing the information recorded at such high density, and a system which can be used therefor. In the present invention, the information is read by reading difference in crystallographic state, crystallographic phase or constituent material as a difference in surface potential or surface charge density.
