Abstract
The front-end system having a capable of 2x reading and writing of BD-R/Ra/ROM is developed. Its readability is improved by adopting 5-tap adaptive partial response maximum likelihood (PRML) with the PR(a,b,c,d,e) type channel. Due to the proposed PRML, less than $2{\times}10^{-4}$ of the bit error rate (BER) is achieved with radial and tangential tilt margin of over${\mp}0.6{\circ}$ on 25GB disc in 2x speed. The method of an optimum Power control (OPC) for stable writing of various BD-R/RE is proposed. The developed chip contains 14-million transistors in a $60mm^2$ dies, and is fabricated in $0.18-{\mu}m$ CMOS technology.
