Abstract:
1. An optical disc device capable of reproducing a hybrid optical disc in which a DVD layer and a next generation DVD layer are arranged, the next generation DVD layer being reproduced with a laser light having a wavelength shorter than a wavelength of a laser light used for the DVD layer and command information for jumping to the DVD layer is recorded on the next generation DVD layer, the optical disc device comprising: a disc determining means for determining that the hybrid optical disc is loaded; a reproducing means for first executing a reproduction process on the next generation DVD layer in preference to the DVD layer when it is determined that the hybrid optical disc is loaded; a jump determining means for determining necessity of a jump to the DVD layer; and a jump controlling means for executing the jump from the next generation DVD layer to the DVD layer according to a determination result by the jump determining means, wherein the jump determining means determines the necessity of the jump to the DVD layer based on the command information acquired by reproducing the next generation DVD layer.
