Abstract
Disclosed is an optical data storage device and a method of making the device. The device has a thin film of a multi-component, phase changeable, chalcogenide material. The thin film is prepared by vacuum deposition of a substantially non-convecting, multi-component, chalcogenide containing first source. The multicomponent source is converted to a non-condensed state, and the non-condensed material is deposited onto the substrate to form a deposit having substantial source/deposit compositional equivalence and the substantial absence of concentration gradients.
