Abstract
We use a new imaging method to resolve the nano scale recording bits on phase-change rewritable optical disks. By this method, several kinds of nano scale recording bits on different phase-change optical disks can be clearly imaged without any painstaking or expensive procedures. With the conductive-atomic force microscopy (C-AFM) images of nano scale recording bits on phase-change materials, we can study the properties of phase-change recording layers and the recording bit formation mechanism comprehensively.
