Patent ID: 8130627

Claim:
An optical disc production apparatus which produces an optical disc that has one or two signal layers, comprising: a first signal layer forming mechanism which forms a first signal layer on a disc substrate; a layer forming mechanism which selectively forms a first reflection layer on the first signal layer on the disc substrate or a second reflection layer on a second signal layer that is formed on the first reflection layer; a second signal layer forming mechanism which forms the second signal layer on the disc substrate on which the first reflection layer is formed on the first signal layer; a light transmission layer forming mechanism which forms a light transmission layer on the first reflection layer or on the second reflection layer; a first transportation mechanism in a looped shape which is provided close to the first signal layer forming mechanism, the layer forming mechanism, the second signal layer forming mechanism and the light transmission layer forming mechanism, and which transports the disc substrate; a second transportation mechanism provided close to the first transport mechanism that transports the disc substrate on which the first reflection layer is formed on the first signal layer or the disc substrate on which the second reflection layer is formed to the light transmission layer forming mechanism; a first transfer mechanism which transfers the disc substrate on which the first signal layer is formed to the first transportation mechanism; a second transfer mechanism that selectively transfers the disc substrate transferred by the first transportation mechanism on which the first reflection layer is formed on the first signal layer or the disc substrate on which the second reflection layer is formed to the second transportation mechanism; and a third transfer mechanism that transfers the disc substrate transferred by the first transportation mechanism on which the first reflection layer is formed on the first signal layer to the second signal layer forming mechanism, and that transfers the disc substrate on which the second signal layer is formed by the second signal layer forming mechanism to the first transportation mechanism.
