1. A trackable optical disc, comprising:
- a first reflective surface comprising a wobble groove trackable by an optical disc reader; and
a plurality of analyte-specific signal elements disposed readably with said wobble groove, said plurality of analyte-specific signal elements arranged in a pattern to thereby function as encoded data,wherein said plurality of analyte-specific signal elements are disposed substantially confocally with said wobble groove such that they are readable by an optical head of the optical disc reader concurrently with said wobble groove.

Abstract
Design, manufacture and use of optical discs that permit the concurrent and discriminable acquisition of signals from both operational features and nonoperational features is presented. The disc geometries and tracking schemes permit such discs to be read in, and data encoded by nonoperational features reported by, standard (or minimally-modified), optical disc readers. Single data layer first and second surface discs are described, as are multiple data layer discs. Use of the disks in analyte-specific assay is presented.
