Abstract: A data writer can have at least a write pole separated from first and second side shields by a continuous dielectric gap layer. Each side shield may have first and second shield sub-layers configured with different magnetic moments that increase relative to the sub-layer's distance from the write pole. The side shields may wrap around a leading tip of the write pole to form a box shield.

Abstract: A data writing device may be constructed and operated with at least a data writer that has at least a write pole and a magnetic feature. A controller may selectively activate the magnetic feature to magnetically oscillate and produce a radio frequency signal proximal the write pole on an air bearing surface (ABS).

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.
