    摘要: An embodiment of the invention is a head for perpendicular recording that has a trailing shield and side shields that are connected to the return pole piece by two studs of ferromagnetic material. The studs extend parallel to the track direction and are located a sufficient distance away from the main pole piece to reduce the flux flow from the main pole piece to the studs. Optionally the studs can be recessed behind the air-bearing surface. The preferred embodiment of the invention is a magnetic transducer with separated read and write heads for perpendicular recording.

    摘要翻译: 本发明的一个实施例是用于垂直记录的头部,其具有通过两个铁磁材料柱连接到返回极片的后屏蔽和侧屏蔽。 螺柱平行于轨道方向延伸,并且距离主极片足够远的距离,以减少从主极片到螺柱的通量流。 可选地,螺柱可以凹入空气轴承表面后面。 本发明的优选实施例是具有分离的用于垂直记录的读写头的磁性换能器。
