Abstract

A large size optical disk (for example, in 300 mm diameter) has been applied to document files and archived coded data files. Recently, demands for larger capacity and higher speed are growing greatly. Therefore, we developed a write once optical disk (300 mm in diameter), which adopts the pit-edge recording method and the MCAV (modified constant angular velocity) method to achieve higher linear density. On optical disk system combining the above two methods has yet been developed. In addition, new techniques must still be developed to satisfy the requirements of large capacity and high speed using these two methods. In this paper, new techniques were have developed are discussed.
