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 polyether-modified organic silicone compound which has a polyoxyalkylene chain, superior in affinity with a binder, in a principal chain or in the principal chain and at both its terminals as shown by the right general formula [where R1 and R2 are -CH3 or -(CH2)p-OCH2 CH2)q)-(OCH2CHR3)r-OH, R3 is a hydrocarbon group of -H or C1-C2, and (p), (q) and (r), (n1), (n2) and n1+n2 are 0-7, 0-50, 0-1,000, 1-500, and <=1,000].
