An optical disk with metal-free phthalocyanine (C32H 18N8, H2PC) and Ag6.0In 4.4Sb61.0Te28.6 layers were prepared. It was possible to readout 200-nm mark with carrier-to-noise ratio of 41 dB that is beyond the resolution limit size. The cross-sectional image confirmed that H2PC is a recording layer forming deformation. Metal particles were found not to be necessary for the super-resolutional readout, and the results should be helpful for understanding the readout mechanism of the super-resolution near-field structure (super-RENS) disk. An advantage of using H2PC recording layer was that it is resistant to temperature increase (∼400°C) induced by the laser irradiation for the super-resolutional readout.
