Abstract:
An optical recording medium structure, comprising:a transparent substrate; a first dielectric layer over the transparent substrate; a first buffer layer over the first dielectric layer; a recording layer over the first buffer layer, wherein the first buffer layer prevents the diffusion of at least one type of element from the recording layer into the first dielectric layer and at the same time prevents the diffusion of at least one type of element from the first dielectric layer into the recording layer; a second buffer layer over the recording layer; a second dielectric layer over the second buffer layer, wherein the second buffer layer prevents the diffusion of at least one type of element from the recording layer into the second dielectric layer and at the same time prevents the diffusion of at least one type of element from the second dielectric layer into the recording layer; an optical compensation layer over the second dielectric layer; and a reflection layer over the second dielectric layer.
