An information recording medium (4) manufacturing method includes steps of forming, on a support (6), a recording layer (8) containing a polymer compound having an azobenzene structure, irradiating the recording layer (8) with first writing light to form a first light-diffracting structure (10) having a three-dimensional relief pattern on the surface of the recording layer (8), fixing the relief pattern by forming a deformation preventing layer (11) on the surface of the recording layer (8), and irradiating the recording layer (8) having the fixed relief pattern with second writing light to forcedly inhibit deformation caused by the movement of molecules, thereby forming a second light-diffracting structure (9) having a refractive index change inside the recording layer (8). |
