ABSTRACT:
A multi-stack optical data storage medium for rewritable recording by a focused laser-light beam, the medium having a substrate with deposited on aside thereof:a first recording stack comprising a phase-change type recording layerat least one further recording stack comprising a phase-change type recording layer,a transparent spacer layer adjacent each further recording stack. The further recording stack is sufficiently transmissive to ensure proper sensitivity for reading and recording in the first recording stack. For this purpose, at least one indium tin oxide layer is present in at least one of the further recording stacks. The indium tin oxide layer further ensures proper cooling behavior of the recording layer of the further recording stack in order to obtain sufficient recording performance in the farther recording stack.
