A manufacturing method of an optical information recording medium includes forming a substrate which has a first main surface and a second main surface, forming a first information signal layer on the first main surface of the substrate, forming an intermediate layer on the first information signal layer, forming a second information signal layer on the intermediate layer, irradiating light from the second main surface side of the substrate and recording identification information on a first region out of the first region and a second region, and forming a barrier layer with regard to the second main surface in the second region which excludes the first region where the identification information is recorded before the recording of the identification information.

A recording medium includes a substrate having a label-side surface on one side and a recording layer for recording and reproducing information on the other side. The label-side surface of the substrate has a mirror surface portion and a rough surface portion, a step having a step height of 10 &#x3bc;m or less is formed between the mirror surface portion and the rough surface portion, and an average roughness of the rough surface portion is between 10 &#x3bc;m and 2 &#x3bc;m, inclusive. Visible information is formed on the label-side surface by using the mirror surface portion and the rough surface portion.

Recording medium and method for manufacturing recording medium

A boundary lubricant filmis formed on a stampercontact portion of a stationary mirrorand/or a stationary mirrorcontact portion of the stamper. The boundary lubricant filmcontains one of kinds of phosphate esters. A material is injected into a cavity. As a result, a disc substrate for an optical disc is molded.

A recording method whereby an inorganic resist made of an incomplete oxide of a transition metal is formed as a film onto a substrate and a latent image corresponding to pits is formed onto the inorganic resist by exposure. The exposure is performed by a laser beam whose intensity has been modulated by a pulse signal whose pulse height decreases in a rear portion in a length direction of the pit, thereby forming a format of a track pitch smaller than a recording beam diameter (track pitch/exposure beam diameter=0.333 to 0.833).

A magneto-optical recording medium from which data is read by using a Kerr effect and which is capable of preventing signal imbalance caused from change in birefringence even in a system in which the amplitude of a reproduced signal is small and the spatial frequency of a shortest record signal train of the magneto-optical recording medium is 1.1&times;NA/&lgr;(line/m) or higher. The photoelastic coefficient of a substrate of the magneto-optical recording medium is 50&times;10,cm,/dyne or smaller. The vertical birefringence of the substrate is 250&times;10,or smaller, the coefficient of water absorption of the same is 0.2 wt % or lower and the thermal coefficient of expansion of the same is 6.5&times;10,cm/cm&middot;&deg; C. or lower.
