초록
The RF signal is distorted since the cross-talk noise from adjacent tracks and ISI(Inter Symbol Interference) is also incresed as recording density is increased. These cross-talk noise and ISI are main reason of reading error for the embossed pits on the disc. In this study we suggest a new coding method, spaced modulation technique and a detection technique for the spaced modulation. We report the result shows detection performance is improved when we use the suggested spaced modulation code and the detection technique instead of conventional modulation code.
