Summary:An optical information medium wherein influence of reflecting light from unnecessary information recording planes is suppressed and spherical aberration can be effectively removed at the time of recording or reproducing in or from the recording medium having a plurality of information recording planes. When a reflectance of the information recording plane is ah and a transmission between the information recording planes is th, the ah and the th of the optical information medium are set to satisfy ((a(h-1)<sup .
