Abstract

In order to improve the storage density of magnetic recording, the shingled magnetic recording method is used. However, this method have a problem of interference between adjacent tracks. Therefore, many studies to prevent the performance degradation due to interference between the adjacent track have been conducted. In this paper, in order to solve inter-track interference, we propose a model to remove inter-track interference. In the case of overlap between tracks is 10% or more, the proposed model shows the performance improvement.

자기기록 장치의 저장 밀도 향상을 위해 인접한 트랙을 겹쳐서 쓰는 방식이 사용되고 있다. 따라서 인접한 트랙간 간섭으로 인한 성능 저하를 방지하기 위한 많은 연구가 진행되어 왔다. 본 논문에서는 인접한 트랙간 간섭을 해결하기 위해 인접 트랙간 간섭을 제거하는 모델을 제안하였다. 트랙간 겹치는 정도가 10% 이상인 경우 본 논문에서 제안한 모델이 좋은 성능을 보인다.
