Abstract
Section titled āAbstractāIn recent years, the information society rapidly developed. It is required to increase density of hard disk drives ļ¼HDDsļ¼. In order to achieve the high density HDDs, it is important to research details of magnetic disk surface and some properties related with the head-disk interface. However, diamond like carbon (DLC) film on disks have been too thin to analyze chemical structure of DLC surface using Raman spectroscopy. In this study, we fabricated the plasmon lens with the sliver thin film on the surface by the vapor deposition and evaluated the structure change of ultra-thin DLC after laser-heating using surface enhanced Raman spectroscopy with the plasmon lens.
