Abstract

Multi-layer recording method has been studied and developed since dual layer disk of DVD-ROM and the studied disk type has expanded from ROM to Rewritable disk. Multi-layer disk has new problems different from a single layer disk. One is an inter-layer cross-talk, which a component of a signal from adjacent layer leaks into a detected signal when the information data is reproduced from a target layer. Second is a recording power fluctuation, which the light power reached a target layer changes by marks on intermediate layers. There were many works that solve this problem. This causes severe problem for signal processing and recording performance. There was work that was proposed to design the structure of a multi-layer disk and an optical head. In this paper, we reported the consideration of a code in order to solve the problems.
