Abstract:
1. An optical disk reproducing apparatus capable of reproducing a hybrid type optical disk which includes a first recording layer which stores data at a first track pitch and a second recording layer which stores data at a second track pitch which is shorter than the first track pitch, the optical disk reproducing apparatus comprising: a memory; a selecting section operable to select one of the first recording layer and the second recording layer; a setting section operable to set reproduction information for the selected layer; an acquiring section operable to acquire an access list of the selected layer from the optical disk and store the acquired access list in the memory; and a reproducing section operable to reproduce the data stored in the selected layer based on the set reproduction information and the stored access list, wherein when a switch request is issued, the selecting section selects another of the first recording layer and the second recording layer and the setting section sets the reproduction information for the currently selected layer; and wherein when a reproduction request is issued after the switch request is issued, the acquiring section acquires an access list of the currently selected layer from the optical disk and stores the currently acquired access list in the memory and the reproducing section reproduces the currently selected layer based on the currently set reproduction information and the currently stored access list.
