Abstract
Inserting germanium nitride thin films between Sb-Te (for super-resolution readout) and ZnS-SiO2 layers was effective to improve super-resolution readout durability of a super-RENS disc using a PtOx-SiO2 write-once recording layer. Waveform of 97-nm (that is below the resolution limit of the optics used) and 340-nm combined marks scarcely changed even after 50,000 times readout. CNR of 100 nm marks was stable (within 3 dB decrease) after 268,000 times readout.
