Improved recording medium and method for producing the same in which a thin lubricant film is applied directly to the surface of the recording medium without the necessity of intermediate layers or additional decomposition steps. The lubricant coating, which is a single monolayer of between about 30 and about 300 angstroms in thickness, is chemically bonded to the surface of the recording medium and the molecules of the film are oriented substantially normal to the surface of the recording medium. The backbone of the molecule of the film is selected from a number of different polymeric materials to provide a desired characteristic to the film surface, such as lubricity, and the distal end of the molecule is preferably provided with a strong electronegative group so that the surface of the magnetic medium is strongly electronegative which further protects against head crash and abrasion due to contact with the magnetic slider head. The film is applied directly to a reactive magnetizable metal surface of the media. The molecules of the film to be applied to the surface are brought to the surface in solubilized form since in this form the molecules are more soluble in the solution than they are in themselves thus promoting orientation of the molecule when the terminal bonding group of the molecule reacts with the surface of the recording medium. |
