Optical information recording medium

A method of recording data to an optical information recording medium, comprising:

• providing a substrate having a through-hole at the central portion thereof, a spiral guiding groove on a surface thereof, a recording layer made of an organic substance containing a dye on the surface, and a cover layer having at least a portion that faces the recording layer and has a modulus of elasticity of about 34 MPa to about 96 MPa at 25° C.;
• and
• deforming a section of the recording layer and a section of the portion of the cover layer away from each other by heating the recording layer and portion sections.

A method of manufacturing an optical information recording medium, comprising:

• forming a reflective layer on a surface of a substrate having a through-hole at the central portion thereof and a spiral guiding groove on the surface thereof;
• applying a recording layer on the reflective layer;
• forming a cover layer from a curable resin on the recording layer, wherein a modulus of elasticity of at least a portion of the cover layer facing the recording layer is in the range of about 34 MPa to about 96 MPa at 25° C.
