Analysis of error correction capability and recording density of an optical disc system with LDPC code

LDPC 코드를 적용한 광 디스크 시스템의 에러 정정 성능 및 기록 용량 분석

In this paper, we evaluated error correction performance and recording density of an optical disc system. The performance of Low-Density Parity Check code (LDPC) is compared to the HD-DVD (BD) ECC. The recording density of optical disc can be increased by reducing the redundancy of the user data. Moreover, since the correction capability of LDPC with decreased redundancy is better than that of BD, the recording density can also be increased by reducing the mark length of the data on the disc surface.
