摘要： The invention is a magnetic transducer with separated read and write heads for perpendicular recording. The write head has a trailing shield that extends from the return pole piece toward the main pole piece to form the write gap at the air-bearing surface. One embodiment of the trailing shield is a two part structure with a pedestal and a much smaller tip that confronts the main pole piece at the gap. In one embodiment a sink of non-magnetic, electrically conductive material is disposed in the separation gap between the read head and the flux bearing pole piece. The sink is preferably made of copper and does not extend to the ABS.

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： Heads for perpendicular recording using a floating-trailing shield as part of the magnetic circuit for writing magnetic domains in the recording media are described. The floating-trailing shield is separated from the main pole piece by a layer of non-magnetic material along its entire length and the air bearing surface of the floating-trailing shield is substantially larger than that of the main pole piece. The reluctance between the trailing shield and the underlayer in the recording medium is made so low that both are at the same magnetomotive force (or potential), so that no direct connection is needed between the floating-trailing shield and the yoke. When the head is used in a storage system with a magnetic recording medium with a soft underlayer, the floating-trailing shield is, in effect, magnetically shorted to the return pole piece during recording. In a second embodiment of the invention the floating-trailing shield extends around the sides of the main pole piece to reduce the off-track magnetic field.
摘要翻译：描述了使用浮动拖尾屏蔽作为用于在记录介质中写入磁畴的磁路的一部分的垂直记录头。浮动后挡板沿着其整个长度由非磁性材料层与主极片分开，并且浮动后挡板的空气支承表面基本上大于主极片的空气支承表面。记录介质中的后屏蔽和底层之间的磁阻被制作得很低以致两者都具有相同的磁动势（或电位），使得在浮动后挡板和轭之间不需要直接连接。当头部用于具有软底层的磁记录介质的存储系统中时，浮动拖尾屏蔽件实际上在记录期间与返回极片磁性短路。在本发明的第二实施例中，浮动后挡板围绕主极片的侧面延伸以减少偏离磁场。
