Abstract
An optical data recording medium of the present invention includes: a substrate; a reflective material layer formed of light-reflective material, the reflective material layer being provided over the substrate; and an optical data recording layer for optically recording data therein and for optically reproducing the data therefrom, the optical data recording layer being formed over the reflective material layer. The reflective material layer is patterned so that the light-reflective material may be partly removed therefrom for selectively allowing a light beam irradiated on the substrate to pass therethrough to reach the optical data recording layer.
