Optical information recording based on photochemical etching of aluminum films

摘要

Abstract: The publication describes optical information recording process based on the photochemical etching of the aluminum films using sandwich-type structures: substrate/aluminum film/polymer light-sensitive layer. The etchers are produced during the illumination of the light-sensitive polymer layers. Processes of the etching have a high light- sensitivity due to additional post-exposure autocatalytic accumulation of the etchers.!8
