<P>PROBLEM TO BE SOLVED: To provide a light scattering body of a light scattering medium in which a scattering coefficient indispensable for reconfiguring an absorber is controlled, and a method for manufacturing the light scattering body. <P>SOLUTION: In an optical information recording medium that includes an optical energy absorber embedded in a three-dimensional light scattering body, the light scattering body is a porous medium and its scattering coefficient distribution is controlled by the size of holes in the light scattering body and the density distribution. The light scattering body as a porous medium is a scattering body manufactured by making a multiplicity of pores inside materials such as glass and polymer resin. Diameter and density are used for parameters for forming the pores. The scattering coefficient distribution of the light scattering body can be controlled by the pore density distribution in the light scattering body. <P>COPYRIGHT: (C)2011,JPO&INPIT |
