Abstract
PURPOSE:To improve the lubricity and wear resistance of a magnetic recording medium by making a magnetic layer contain a specific organic silicone compound as a lubricant. CONSTITUTION:A magnetic layer is made to contain a poly-ether-modified organic silicone compound which has a polyoxyalkylene chain with a fatty-acid residual group, superior in affinity with a binder, in a principal chain or in the pricipal chain and at both its terminals as shown by the right general formual [where R1 and R2 are -CH3- or -(CH2)p-(OCH2CH2)q-(OCH2CHR3)r-OOCR4, R3 and R3 are hydrocarbon groups of -H or C1-C2, and C1-C26, (p), and (q) and (r), (n1), (n2), and n1+n2 are 0-7, 0-50, 0-1,000, 1-500, and <=1,000].
