    • An optical disk apparatus according to the present invention includes: a controller 111, which receives an instruction that a layer-to-layer jump be performed from a current layer to a target layer; a layer-to-layer jump control section 146, which adjusts a spherical aberration correction value to the target layer and then gets the layer-to-layer jump attempted; a decision section 146 for determining whether the layer-to-layer jump has been carried out successfully; and a layer determining section 146 for determining, if the focus position has been set on a non-target storage layer as a result of the layer-to-layer jump, where the non-target storage layer is located in the optical disk. The layer-to-layer jump control section 146 shifts the focus position of the light beam from that non-target storage layer to the target layer by reference to information indicating which of the multiple storage layers the non-target storage layer is.
