High density data storage devices with a lubricant layer comprised of a field of polymer chains

Systems in accordance with the present invention can include a tip contactable with a media, the media including a phase change material disposed over a substrate, a lubricant layer disposed over the phase change material, and optionally an overcoat disposed between the phase change material and the lubricant layer. The lubricant layer can include polymer chains (also referred to herein as polymer fibers), the polymer chains being adapted to bond to one of the phase change material and an overcoat. Where an overcoat is used, the overcoat is a highly anisotropic material that conducts current more efficiently through the overcoat than across the overcoat. The media is either grounded or electrically connected with a voltage source such that when the tip is placed in contact with the media and a voltage is applied to the tip, a current is drawn through the media. The lubricant layer reduces wear on the tip by providing a movable surface that does not stick to the tip, but rather holds to the bonded surface.
