Abstract: A write head having reduced dimensions. In one implementation, the write head has a main pole having a leading side and a trailing side, a leading yoke on the leading side of the main pole, and a coil wrapped around the main pole and the leading yoke. The coil on the leading side and the leading yoke having a distance of no greater than 300 nm therebetween, and the coil on the trailing side and the main pole having a distance of no greater than 350 nm therebetween. In an alternate implementation, the write head has a trailing yoke, with the coil on the trailing side and the trailing yoke having a distance of no greater than 350 nm therebetween.

Abstract: A magnetic element may be generally configured as a data writer constructed at least with a write pole positioned within and separated from a box shield by a write gap. The box shield may be configured to maintain at least a separation distance from a first side of a leading edge of the write pole to an opposite second side of the leading edge.

Abstract translation: 通常将磁性元件配置为数据写入器，至少写入写入磁极位于盒屏蔽内并由写入间隙分离。 盒式屏蔽可以被配置为保持与写入极的前缘的第一侧至前缘的相对的第二侧的至少间隔距离。
