プレーナー型マルチトラック垂直磁気記録ヘッドの検討

抄録

We propose a multi-track head for perpendicular magnetic recording, with a planar configuration. The planar multi-track (PMT) head consists of four single-pole write heads and two ring-yoke spin-valve MR read heads. It is used for multi-track recording on a hard disk medium without any writing interactions in recording performances. Magnetic-force-microscopy (MFM) observations were made to confirm the success of multi-track recording.
