Abstract

In the future, in order to popularize multimedia network services into the home, the network file storage systems will have to possess a huge storage capacity and an ultra-high data transfer rate¹⁾. Various studies have recently been undertaken to increase the recording density using short wavelength lasers²⁾ and super resolution technologies.³⁾ Data transfer rates have been increased using multiple beams.⁴⁾ However, it still might be difficult to attain these goals by conventional optical disk recording method.
