8-8 2層媒体を用いた光磁気システムのための4値記録符号の開発 [in Japanese] Construction of Quaternary Code for Magneto-Optical Recording System using Double-layer Media [in Japanese]
Access this Article
The use of multi-layer media has been expected to improve linear recording density on magneto-optical (MO) system. However, the conventional technique for MO system using double-layer media is obliged to bring the large change of magnetic field with the transition on recording level. This paper proposes a new method how to construct a quaternary code for it in which we can deal successfully with such problem.
