摘要： There is provided a magnetic recording medium which exhibits superior lubricating properties and superior tape-transport properties as well as superior robustness even in a low-temperature environment. A magnetic layer containing a ferromagnetic metal is formed on a nonmagnetic support, and a protecting film is formed on the magnetic layer. A lubricant auxiliary coating composition comprising an aromatic alcohol is applied to the protecting film to form a lubricant auxiliary layer, and a lubricant coating composition comprising a compound represented by the formula (1) below is applied to the lubricant auxiliary layer to form a lubricant layer. R1CH(COOR2)CH2COOR3 (1) wherein R1 represents an aliphatic alkyl group, an aliphatic alkenyl group, or a hydrogen atom, and each of R2 and R3 independently represents a fluoroalkyl group, a fluoroalkenyl group, a fluoropolyether group, or a hydrogen atom.

摘要： The present invention provides a lubricant capable of holding an excellent lubricating property under various types of service conditions, maintaining a lubricating effect for a long period of time and providing excellent traveling property, abrasion resistance, durability and the like, a recording medium using the lubricant and a carboxylic acid type compound constituting the lubricant. The lubricant is formed by using a carboxylic acid type compound having at least two carboxyl groups and one ester bond as represented by the following general formula (1) (for example, a compound as represented by the following chemical formula (1)) as a constituting mixture and, then, the thus-formed lubricant is allowed to be contained on or in a recording layer of the recording medium: in which Rf represents a non-substituted or substituted, saturated or unsaturated, fluorine-containing hydrocarbon group or hydrocarbon group; Es represents an ester bond; and R may be omitted or represent a non-substituted or substituted, saturated or unsaturated hydrocarbon group.
