Abstract
Aspects include recording media with enhanced areal density through reduction of head media spacing, head keeper spacing, or head to soft underlayer spacing. Such aspects comprise replacing currently non-magnetic components of devices, such as interlayers and overcoats with components and compositions comprising magnetic materials. Other aspects relate to magnetic seed layers deposited within a recording medium. Preferably, these aspects, embodied as methods, systems and/or components thereof reduce effective magnetic spacing without sacrificing physical spacing.

An apparatus comprising:
- a soft magnetic underlayer (SUL) on a substrate;
- a magnetic recording layer over the SUL;
- a ferromagnetic media overcoat on top of the magnetic recording layer;
- and
- a ferromagnetic interlayer between the SUL and the magnetic recording layer.
An apparatus comprising:
- a soft magnetic underlayer (SUL) on a substrate;
