• A multilayer disk without a guide groove can be a large-capacity and price-competitive optical disk. We propose a novel tracking servo system that is robust and accurate for disks without grooves. We use only one reference layer for which the linear positioning method is employed, which enables us to obtain tracking servo information over the whole disk radius. We also use an adjacent track servo system so as not to overwrite the previous track. We confirm the stability and performance of the system with a simulation.
