Abstract: PURPOSE: To always impart the required amt. of a lubricant by incorporating a porous pigment having 300-1,000m /g BET specific surface area into the surface layer part of a magnetic layer by 1-10wt.% of the amt. of a magnetic material when at least one side of a nonmagnetic substrate is coated with the magnetic layer. CONSTITUTION: When at least one side of a nonmagnetic substrate is coated with a magnetic layer, this magnetic layer is made of a magnetic material finely dispersed in an org. binder and a porous pigment having 300-1,000m /g BET specific surface area is incorporated into the surface layer part of the magnetic layer by 1-10wt.%, preferably 2-6wt.% of the amt. of the magnetic material so as to reduce friction. The pigment is made of a molecular filter based on metal-aluminum silicate having a special crystal structure and the spaces in a three-dimensional network structure are formed by the reaction of aq. solns. of sodium aluminate and sodium silicate. Sticking effect is also reduced.

Abstract: PURPOSE: To improve wear resistance and corrosion resistance by forming a hydrogen-contg. amorphous carbon protective layer by vapor deposition while adding a hydrocarbon gas. CONSTITUTION: A ferromagnetic metal thin layer such as Co-P and a carbon protective layer (A) are formed on a nonmagnetic carrier to obtain the medium of the title. The layer (A) is a hydrogen-contg. amorphous carbon layer of 5-100nm thickness formed by vapor deposition which uses a carbon target, while simultaneously adding a hydrocarbon gas which is decomposed by the vapor deposition plasma to change into a vapor deposition gas. As for the vapor deposition, a carbon target DC magnetron vapor deposition method is preferably used, and acetylene is added by (1:0.05) to (1:1) partial pressure to the sputtering gas such as Ar.

Abstract: PURPOSE: To provide a belt piece surface treatment device by which it is surely compensated to effectively reduce surface irregularity of a belt piece of a material to be treated and further, the treatment is performed coping with individual conditions of each belt piece to be treated. CONSTITUTION: A surface treatment device for a belt piece material to be treated is provided with a blade 4 arranged orthogonal to a transfer path of a belt piece material to be treated 2 and a partitioned room 8 which is placed in parallel and closely to the blade, being open to the above-mentioned transfer path, and being connected with a pressure reducing device, and the opening 9 is positioned under an acting edge 10 of the blade.
