制备了含无金属酞菁(C32H18N8，H_2PC)和Ag6.0In4.4Sb61.0Te28.6层的光盘。可以读出超过分辨率极限尺寸的载噪比为41db的200 nm标记物。横截面图像证实了H_2PC是记录层的形成变形。发现金属粒子不是超分辨读出所必需的，这一结果将有助于理解超分辨近场结构(Super-RENS)盘的读出机制。使用H_2PC记录层的一个优点是它能抵抗激光照射引起的温度升高(∼400°C)，用于超分辨率读出。
An optical disk with metal-free phthalocyanine (C32H18N8, H2PC) and Ag6.0In4.4Sb61.0Te28.6 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.
