MAGNETIC HEAD, HEAD ASSEMBLY, AND MAGNETIC RECORDING/REPRODUCING APPARATUS TO REDUCE RISK OF WIDE AREA TRACK ERASE |
摘要 |
A magnetic head includes a main magnetic pole layer and a yoke layer. The main magnetic pole layer generates a magnetic flux of a recording magnetic field and includes a magnetic pole front part and a magnetic pole rear part. The yoke layer is disposed at the magnetic pole rear part and includes a yoke front part and a yoke rear part. The magnetic pole front part extends on a magnetic medium-facing surface side of the magnetic pole rear part with a width in a track width direction being smaller than that of the magnetic pole rear part. The yoke front part extends on the magnetic medium-facing surface side of the yoke rear part with a width in the track width direction being larger than that of the magnetic pole rear part and that of the yoke rear part. |
