Abstract
An apparatus, system and method for magnetic recording are disclosed. In at least one embodiment, the apparatus includes a first portion of a first magnetic medium having a first cross-sectional area, and a second portion of a second magnetic medium having a second cross-sectional area. The first and second portions are joined by way of a junction that allows for at least some ferromagnetic coupling therebetween. Additionally, the first and second cross-sectional areas are of differing extent in a first dimension so that a first ledge portion of one of the first and second portions extends past a first edge of the other of the first and second portions.
