Abstract

The super-resolution near-field structure (super-RENS) disc system is the most promising one for next-generation optical data storage systems to succeed the Blu-ray disc (BD). In this paper, we apply the simplicial canonical piecewise-linear (SCPWL) model to modeling super-RENS read-out signals since reliable and accurate channel modeling is essential for performance analysis and development of equalizers for super-RENS systems. The validity of this model is verified using radio frequency (RF) signal samples obtained from a super-RENS disc, The experiment results on modeling indicate that the SCPWL model can be efficiently utilized for the nonlinear modeling of the super-RENS systems.

Super-RENS (Super-Resolution Near-field Structure) 디스크 시스템은 BD (Blu-ray Disc) 이후의 차세대 광 기록 저장 시스템의 유망한 후보이다. 따라서 super-RENS 시스템을 위한 등화기 개발과 성능 분석을 위해 정확하고 신뢰성 있는 채널 모델링은 매우 중요하다. 본 논문에서는 super-RENS 시스템의 모델링을 위해 SCPWL (Simplicial Canonical Piecewise-Linear) 모델을 적용하고자 한다. Super-RENS 디스크로부터 획득한 RF 신호 샘플들을 사용하여 모의실험을 수행한 결과, super-RENS 시스템의 비선형 모델링을 위해 SCPWL 모델이 효과적으로 활용될 수 있다는 것을 확인하였다.
