Rewritable optical data storage medium and use of such a medium

A description is given of a phase-change optical data storage medium ( 20 having a recording stack ( 2 ) with a recording layer ( 6 ) and a metal reflective layer ( 3 ) comprising at least one transparent layer ( 4, 8 ) of the material indium tin oxide (ITO). Use of an ITO layer ( 4, 8 ) in the reco...

Summary:A description is given of a phase-change optical data storage medium ( 20 having a recording stack ( 2 ) with a recording layer ( 6 ) and a metal reflective layer ( 3 ) comprising at least one transparent layer ( 4, 8 ) of the material indium tin oxide (ITO). Use of an ITO layer ( 4, 8 ) in the recording stack ( 2 ) improves the cooling behavior of the recording layer ( 6 ) combined with good optical contrast. Thus, higher possible data rates are achieved.
