Near-Field Readout of 75 Gbyte Disc Made with Conventional Optical Disc Manufacturing Equipment

Abstract

In this report, the results of the study of a 75 Gbyte (GB) disc for the solid immersion lens (SIL) system are presented. We used conventional mastering and molding equipment except for the recording process for the SIL disc. The electron beam recorder (EBR) was used as a signal recording machine for small pits. From the results of the experiments, we confirmed that conventional equipment could be used for high-density disc manufacture. The jitter value of the 75 GB disc was 9.5%.
