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.
