Abstract

The possibility of ultrahigh density recording has been shown using an overwritable phase change optical disk with a Ge-Te-Sb recording film. It was found that recording marks of 0.2 micrometers length can be formed stably and that high contrast ratio can be obtained in the wide range of wavelength. From these results, about six times as high linear density as the existing format is possible by using mark-edge recording or MCAV method. It was also found that the crosstalk of PCE optical disk is so small that double track density recording is possible by track pitch reduction or groove/land recording. These results show a possibility of large capacity of 10 GB for 5.25 inch diameter disk.
