Magnetic recording medium

Abstract

Abstract PURPOSE:To obtain a magnetic recording medium having excellent durability by using at least one kind of specific ester lubricating agents alone or in combination with other lubricating agents. CONSTITUTION:At least one kind of the ester lubricating agents expressed by formula I are used alone or in combination with the other lubricating agents. In formula, R1 denotes a satd., unsatd. or branched alkyl group or >=6C; R2, R3 denote a straight chain or branched alkyl group of >=4C; X denotes a straight chain or branched alkyl group of >=1C. The coefft. of friction of the magnetic recording medium is thereby lowered and particularly the coefft. of friction at a low temp. is lowered, by which the traveling performance and durability of the magnetic recording medium are improved.
