    Abstract: A method, in one embodiment, can include pumping a gas into a reservoir that includes a lubricant. In addition, the method can include changing the gas into a supercritical fluid that extracts lubricant molecules from the lubricant resulting in a mixture of the supercritical fluid and the lubricant molecules. Furthermore, the method can include utilizing the mixture to deposit a lubricant molecule onto a magnetic media.

    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.
