Abstract: A wobble detection device includes a sensor unit. The sensor unit includes a one-dimensional image sensor and a one-dimensional image sensor arranged side by side in an auxiliary scanning direction so that their corresponding pixels coincide with each other in a main scanning direction, and acquires an image of an object moving in the auxiliary scanning direction as one-dimensional data. The wobble detection device makes a comparison of data corresponding to the same image region by using one-dimensional data acquired by the one-dimensional image sensor and one-dimensional data acquired by the one-dimensional image sensor and thereby detects a movement amount of the image in the main scanning direction between a time when the one-dimensional data used for the comparison was acquired and a time when the one-dimensional data used for the comparison was acquired.

Abstract: In a multilayer optical disc having information layers conforming to a plurality of different optical disc standards, because the type of each information layer is not recorded in the other information layers, in read and write operations by a compatible optical disc device conforming to a plurality of optical disc standards, every time the information layer being accessed changes, it has been necessary to read the type of the information layer and select a method of generating a tracking error signal adapted to the type of information layer, so access has taken time. In order to solve the above problem, in the optical multilayer disc according to the present invention, having information layers conforming to a plurality of different optical disc standards, in an area in one of the information layers, information about the other information layers is recorded. The time required to access the other information layers can be reduced by using this information to select a tracking error signal generating method.
