Abstract
This invention relates to optical discs that preferably include multiple data layers and are configured to receive analytes which can be detected by an optical disc reader. The optical disc reader may be a standard optical disc reader or an optical disc reader modified therefrom. The optical disc may include (1) a first layer including optically readable structures which have encoded tracking information, and speed information enabling an optical disc reader to rotate the optical disc at a speed that is determinable from the speed information; (2) a second layer including optically readable structures; and (3) an analyte section capable of receiving an analyte which can be read by the optical disc reader.
