Abstract: A multilayer optical information recording disk comprising a plurality of recording layers and intermediate layers provided between the plurality of recording layers, and a method for manufacturing the same are provided. At least one of two intermediate layers disposed adjacent to respective sides of one recording layer is made of adhesive. Each of the recording layers includes a polymer binder and a dye dispersed in the polymer binder or includes a polymer to which a dye is bonded. Each recording layer is configured such that the dye absorbs a recording beam and generates heat which deforms the recording layer, causing an interface between the recording layer and the intermediate layer made of adhesive to have a protrusive shape protruding into the intermediate layer, thereby recording information thereat. The interface between the recording layer and the recording layer made of adhesive has a groove for track-following servo control.

Abstract: A mold equipped with a substrate having a fine pattern of protrusions and recesses and a mold release layer formed along the pattern of protrusions and recesses on the surface thereof is employed to press resist coated on a substrate, to form a resist pattern, to which the pattern of protrusions and recesses is transferred. The thickness of the mold release layer and the pressing force with which the mold is pressed against the resist are controlled such that the line width of the resist pattern becomes a desired value. The width of the lines of the resist pattern is controlled by this configuration.
