method of manufacture of an optically readable information disk support, using a flat plate termoconduttiva of hardening of inorganic material

摘要

A transparent disc 1 carries a reflecting crenellated information structure 2 which is bonded to a flat heat- conducting plate 6, for example an aluminium plate, to reduce the amount of local heating, with consequent degradation of the information structure 2, which may be caused by the playback beam.
