Patent ID: 7680006

Claim:
A recording apparatus comprising recording light illuminating means for illuminating recording light on an optical recording medium having a plurality of recording layers, said optical recording medium including a n-th (n≧1) recording layer at least having a substrate and a semi-reflective layer for partially reflecting and partially transmitting the incident light, formed on said substrate, a (n+1)th recording layer at least having another substrate and a reflecting layer for reflecting the light, incident thereon, formed on said another substrate, and a light condensing layer for collecting the light incident through said n-th recording layer on said (n+1)th recording layer; an objective lens for condensing the recording light illuminated by said recording light illuminating means on said optical recording medium; and focusing control means for controlling the focusing of said objective lens; said focusing control means, in recording data on an n-th recording layer of said recording medium, controlling the focusing position of said objective lens so that the light will be focused on the organic dye material formed on the n-tb recording layer; said focusing control means, in recording data on an (n+1)th recording layer of said recording medium, controlling the focusing position of said objective lens so that the light will be focused on the organic dye material formed on said (n+1)th recording layer through said light condensing layer.
