• We propose a recordable multilayer super-resolution method (discrete-track three-dimensional pit selection) to realize an optical disc with a sub-terabyte data capacity. The fundamental super-resolution characteristics of a discrete-track (DT) super-resolution disc were experimentally examined comparing to that of the conventional super-resolution disc. The experimental results show that the DT super-resolution disc exhibits high optical resolution equal to that of the conventional disc and an optical transmittance of 71%, sufficient for multilayer super-resolution. The results of the disc design indicated the possibility of a data capacity of 500 GB/disc.
