Beschreibung
Zusammenfassung:	A method is provided for the manufacture of optical recording media by forming a reflective layer, recording layer and transparent layer on a substrate in this order utilizing appropriately set formation conditions. The reflective layer, recording layer and transparent layer are formed upon the substrate in this order and the deposition rate for said recording layer is set to 5 nm/sec or greater, thereby enabling manufacture of optical recording media with little jitter. The deposition rate for the recording layer is preferably set to 50 nm/sec or less, and the deposition rate for the reflective layer is preferably set to 15 nm/sec or greater.
