Writer design with enhanced writability |
摘要 |
A perpendicular magnetic recording (PMR) head is fabricated with a main pole and a trailing edge shield having surfaces and interior portions that may include synthetic antiferromagnetic multi-layered superlattices (SAFS) formed on and/or within them respectively. The SAFS, which are multilayers formed as periodic multiples of antiferromagnetically coupled tri-layers, provide a mechanism for enhancing the component of the writing field that is vertical to the magnetic medium by exchange coupling to the magnetization of the pole and shield and constraining the directions of their magnetizations to lie within the film plane of the SAFS. |
