| 摘要 |
This invention provides a magneto-optical recording medium comprised of a substrate, a base layer of zinc oxide or indium oxide sputtered onto the substrate and a multilayer recording film sputtered onto the base layer of zinc oxide or indium oxide, wherein the base layer of zinc oxide or indium oxide is from about 200 A to about 4500 A (about 20 nm to about 450 nm) thick, preferably from about 200 A to about 2000 A (about 20 nm to about 200 nm) thick, the multilayer recording film is a platinum/cobalt or a palladium/cobalt multilayer film consisting of alternating layers of platinum and cobalt or palladium and cobalt, and the substrate is transparent to the radiation used to record and read. |
