摘要：
A multi-layer data storage medium includes a plurality of recording layers in which a guide groove, where data is stored, is formed in a spiral manner, and each center of the plurality of the recording layers is eccentric to a center of the multi-layer data storage medium in a different direction. A method of identifying a recording layer of the multi-layer data storage medium is also described.
