Optical recording provided with a chalcogenide recording layer

摘要

Optical recording element in which a transparent supporting substrate of a synthetic resin or provided with a coating layer of synthetic resin has a chalcogenide recording layer provided on one side of the synthetic resin and which recording layer is protected by damage from continuous laser light used for reading information recorded in the recording layer by a thermally conductive layer of chromium present on at least one surface of the chalcogenide recording layer.
