INFORMATION RECORDING METHOD

摘要

A method of recording information in a laminated structure (003) including an intermediate layer (007) located between a transparent layer (006) and a non-absorbing layer (008). The method includes the steps of subjecting the laminated structure (003) to a pulsed beam of laser radiation so that the beam passes through the transparent layer (006) to be absorbed by the intermediate layer (007) to ablate areas of the intermediate layer (007), thus recording information in the laminated structure.
