    摘要： A magnetic recording medium comprising a non-magnetic substrate and a magnetic layer and a protective layer which are formed on the non-magnetic substrate in that order, wherein a substance(s) as a single component or a plurality of components, which constitute a liquid continuously supplied to the surface of said protective layer, are adsorbed on or react with the surface of said protective layer to form a lubricating film having low frictional properties and low wearing-out properties. The present invention can realize negligible friction and wear resistance even in severe sliding at a very slightly kept-off or completely contacted state by continuous supply of a liquid lubricant prepared by adding a fluoro compound and an extreme pressure agent or an oiliness agent to a solvent to the surface of a disc, and can provide a magnetic recording reproducer having excellent sliding-resistant characteristics.

    摘要： A lubricating film is provided for a magnetic disk having a data region and a CSS region formed on its surface. The lubricating film ensures low stiction and good resistance to contact sliding in the data region and also ensures good CSS durability in the CSS region. Therefore, it is possible to provide a magnetic disk and a magnetic recording/reproducing device which do not cause problems with sliding between the magnetic head and the magnetic disk while the apparatus is running normally and even when the apparatus stops accidentally. The lubricating film formed in the data region of the magnetic disk is firmly fixed to the surface of the magnetic disk and is hardly liable to stiction. In addition, it is thick enough to ensure good durability even in the case of contact sliding. The lubricating film formed in the CSS region is composed of a lubricant which is firmly fixed to the surface of the magnetic disk and another lubricant which is weakly fixed to the surface of the magnetic disk; therefore, it is superior in CSS durability. This contributes to the highly reliable magnetic disk and magnetic recording/reproducing device.

    摘要： A substantially water-free, emulsion type liquid lubricant for metal forming which comprises:(a) a lubricating oil,(b) at least one of phosphoric acid esters represented by the general formula: ##STR1## wherein R is alkyl, alkylalkenyl or aryl; n is an integer of 1 to 2, and (c) an emulsifying agent,an average particle size of the phosphoric acid ester being 0.3 to 120 .mu.m, can form a lubricating film having distinguished heat resistance and lubricating properties by virtue of the heat generated by deformation and friction during the metal forming only by wetting the surface of a metallic workpiece or a die or both with the lubricant and work effectively for preventing galling, and thus parts with a high reduction of area or parts of complicated shapes can be readily formed.A lubricating film having a lubricating effect equivalent to that of the conventional phasphate film can be simply obtained, greatly contributing to reduction in product cost.An emulsion type liquid lubricant having a prolonged emulsion stability can be prepared through emulsification with a high speed mixer having a stirring blade with wiremesh-like fine perforations, and thus articles or parts with uniform quality can be formed.
