We have delivered an idea, based on multiple level coding, to read and write with the multiple level tracking system. By utilizing off-track recording and multi-level coding, we may increase the track density to expand the optical disc density. Off-track recording is a design using LC diffractive optical element (LCDOE) to control the recording beam in desired angle. Another beam is for reading and tracking.
