| 摘要 |
A thin film, perpendicular write head for use with recording media with or without a soft under layer is disclosed. The present invention comprises an tapered auxiliary pole, situated below the main write pole and separated from the write pole by a lower non-magnetic gap. The auxiliary pole alleviates problems such as erasure after write, and cross track stray erasure fields, associated with operating conventionally designed perpendicular writes heads with media having no soft under layer.
