Abstract

The shingled magnetic recording method has interference between adjacent tracks. Furthermore, when read-head reads the data along the track, the head can be skewed by some physical effects. In this paper, in order to solve this problem, we propose a two-dimensional equalizer that uses two heads. If the head is skewed, it is possible to complement the performance by positioning the two heads at the center of the current track.

트랙을 겹쳐서 쓰는 자기기록 방식은 인접한 트랙간 간섭이 심하게 발생한다. 또한 리드헤드가 트랙을 따라 돌면서 데이터를 읽을 때, 물리적인 영향으로 헤드가 틀어질 수 있다. 본 논문에서는 이러한 문제들을 해결하기 위해 두 개의 헤드를 사용하는 이차원 이퀄라이저를 제안하였다. 헤드가 틀어진 경우 두 헤드의 위치를 현재 트랙의 중앙에 위치시킴으로 성능을 보완할 수 있다.
