摘要: A write once read many (WORM) type optical recording medium and an method therefor are provided. The has a multi-functional layer (2) functioning as both reflective layer, protective (3), sequentially formed on substrate (1). This can be manufactured simply due to its simple structure provides good sensitivity compatibility with CD player using laser beam of wavelength 400-850nm. Also, in the for information WORM medium, substrate, all participate mechanism form bump.
