The present invention includes an apparatus and method for depositing diamond on a substrate. A hydrocarbon/hydrogen gas mixture is passed through a refractory metal hollow cathode which is self heated to a high temperature. The gas mixture is dissociated by a combination of thermal and plasma effects. The plasma plume emanating from the hollow cathode heats the substrate which is positioned on a surface of the anode. Growth of the diamond film is enhanced by bombardment of electrons.

The invention is a recording medium wherein the light absorptive layer is a granular material comprising domains of a light sensitive material embedded in a dielectric matrix. The domains comprise a material which can be reversibly switched from a first state to a second state having different optical properties by the absorption of light. The matrix is composed of a material which is effective for inhibiting the formation of an irreversible change in the optical properties of the absorptive layer. The invention further comprises this optical recording medium having an information track recorded therein as a series of regions in the absorptive layer wherein the domains have been reversibly switched to a second state having different optical properties.
