Abstract
In each of at least two information layers () which constitute a information recording medium having a plurality of information layers on its one side, the compositions of the recording layer () and the dielectric layers () adjacent to the recording layer () in one information layer () are common to the compositions of the corresponding layers () in the other information layer, so that the recording layers () and the dielectric layers () and () in the two information layers () can be formed in common sputtering film-forming chambers without the replacement of targets, which makes it possible to produce a multi-layer single-sided recording medium with a decreased time loss in the production process.
