트랙 폭이 97μm인 넓은 쓰기 헤드와 트랙 폭이 2.7μm인 좁은 읽기 헤드를 사용하여 측정된 오프 트랙 특성을 고려하여 기준선 이동의 원인이 논의되었습니다. 읽기 헤드가 트랙 가장자리에 가깝게 이동하면 기준선 이동이 증가했습니다. 트랙 가장자리를 넘어선 기준선 이동은 음수 값으로 감소했습니다. MIG 헤드와 MR 헤드의 리드백파로부터 수직자화에 대한 MR 헤드의 임펄스 응답 곡선을 추정하였다. 응답 곡선은 녹음된 트랙 폭에 따라 달라집니다. 기록된 트랙이 좁을 때 응답 곡선의 언더슈트는 트랙 폭이 무한한 2D 이중 간격 링 헤드 모델을 기반으로 한 헤드 필드의 언더슈트보다 작았습니다. 이 작은 언더슈트는 기록된 자화의 DC 성분의 감도를 유도하고 기준선 이동을 유발합니다. 좁은 트랙 기록을 사용하는 단일 레이어 수직 기록 매체에 대한 MR 헤드의 리드백 파동을 계산하려면 기록된 트랙 가장자리의 표유 자기장의 효과가 읽기 헤드의 임펄스 응답 곡선에 포함되어야 합니다.

Abstract: The origins of baseline shift were discussed considering the measured off-track properties using a wide write head with track widths of 97 µm and a narrow read head with track widths of 2.7 µm. The baseline shift increased when the read head was moved close to the track edge. Beyond the track edge, baseline shift decreased to negative values. The impulse response curve of the MR head to the perpendicular magnetization was estimated from the readback waves of the MIG head and the MR head. The response curve depended on the recorded track width. When the recorded track was narrow, the undershoot of the response curve was smaller than that of the head field based on the 2D double-gap ring head model with infinite track width. This small undershoot induces sensitivity of the DC-component of the recorded magnetization and causes the baseline shift. To calculate the readback waves of the MR head for single-layer perpendicular recording media with narrow-track recording, the effect from stray field at the recorded track edge must be included in the impulse response curve of read head.
