摘要:
An optical information recording medium having a drawing region capable of being used without being reversed and without interference with a data recording region is disclosed. The optical information recording medium has a structure in which a recording layer, a semitransparent reflective layer, a discoloration layer, and a protective layer are is formed in order on a first light-transmitting substrate so that the discoloration layer is irradiated with a laser beam to change the optical property of the discoloration layer. For example, interaction between a colorant and a developer in the discoloration layer which assumes a black color is eliminated to cause the color to disappear, thereby forming an image.
