The mechanism of the aperture-type Blu-ray super-resolution near-field phase change optical disk with a mask layer of Sb2Te3 was studied theoretically and experimentally. Optical and thermal simulations were carried out to study the relationships of carrier-to-noise ratio (CNR) with reading speed and power. The theoretical prediction results were in good agreement with the experimental results. It was found that a thermal shield layer (TSL) with a high thermal conductivity, which is inserted into the dielectric layer sandwiched by a mask layer and a phase change layer, can significantly enhance readout thermal stability for the super-resolution near-field structure (super-RENS) optical disk.
