PURPOSE:To improve lubricity and wear resistance and durability by depositing a fluorine lubricating agent via an organo aluminum compd. which is first deposited on the surface of a magnetic layer on said surface thereby depositing and forming securely two lubricant layers having excellent lubricity on the surface of the magnetic layer. CONSTITUTION:A fluorine lubricating agent is deposited via an organo aluminum compd. on the magnetic layer on a base plate. The organo aluminum compd. is dissolved in a suitable solvent such as toluene and the magnetic layer is immersed in the soln. or the soln. is coated or sprayed on the surface of the magnetic layer, on which a soln. prepd. by dissolving the fluorine lubricating agent in a suitable solvent such as freon is coated. If the coating is subjected to a heat treatment, for example, for 0.5hr at 70 deg.C, the organo aluminum compd. is more securely deposited on the surface of the magnetic layer and durability and corrosion resistance are additionally improved. Such organo aluminum compd. is deposited within a range of 0.1-25mg/m<2> and the fluorine lubricating agent within a range of 0.1-50mg/m<2>. |
