Abstract: An optical recording medium and a method for manufacturing an optical recording medium from a first substrate having a first surface and a second substrate having a second surface facing the first surface of the first substrate. At least one of the first and second substrates includes an information recording layer. An adhesive material is selectively applied to one of the first and second surfaces. The first surface of the first substrate is then positioned in close facing engagement with the second surface of the second substrate, and the first and second substrates are adhered under predetermined partial vacuum conditions. Preferred materials, adhesives, viscosity of the adhesives, pressures for adhering the substrates, and degree of vacuum are disclosed.

Abstract: An optical recording medium having two adhered substrates one of which has a magneto-optic recording layer thereon and the other of which has at least one dielectric layer thereon so as to improve stability and weatherability. The dielectric layer is a transparent oxide, a nitride or a mixture of an oxide and a nitride and has a thickness between about 30.ANG. and 10 .mu.m. In an especially preferred embodiment, neither substrate is provided with any layers in either the internal area or the circumferential area of a disk and the substrates themselves are exposed and adhered together with adhesive.
