Magnetic recording apparatus comprising a magnetic recording medium and a magnetic head each coated with a coating of a binder and a specified fluorolubricant

摘要

A magnetic recording medium which comprises a non-magnetic substrate, a thin film magnetic layer formed on the surface of the substrate and an organic thin film protective layer formed on the magnetic layer, the organic thin film protective layer having a thickness of not more than 100 nm and containing a filler having a particle size of not more than 50 nm, wherein the surface of the organic thin film protective layer is further coated with a fluorine-based compound represented by the following general formula: F(C3F6-I-)x-C2F4-, F(C3F6-O-)x-(CF2O)y-(CF2)z-or -(C2F4-O-)y-(CF2-CF2- , wherein x, y and z are integers of 1 or more, and a magnetic head whose surface is coated with a lubricant thin film having the same composition as that of the above organic thin film protective layer have an excellent sliding durability, and a magnetic recording apparatus using these magnetic recording medium and magnetic head has a high reliability.
