Application of Nanometer-Scale Processing Technique in High-Density Recording


Article Preview

To realize ultrahigh density recording in high precision using polycarbonate as a recording media, the nanometer-scale mechanical processing properties of polycarbonate and fluorocarbon plasma-treated polycarbonate were investigated using atomic force microscopy (AFM). The surface free energy of the polycarbonate specimen can be reduced by fluorocarbon plasma-treatment, resulting in processing force being reduced. Thus, nanometer-scale precise processing of polycarbonate can be realized. Lines and spaces with intervals minimized to 60 nm were performed on the fluorocarbon plasma-treated polycarbonate. Viscoelastic properties of the fluorinated polycarbonate were evaluated using AFM in force modulation mode. Fluorocarbon plasma treatment can reduce friction force of a polycarbonate sample and improve its wear resistance. Therefore, the friction durability corresponding to the reliability of data reproduction was markedly improved.
