Abstract

PURPOSE: To improve the smoothness, hardwearing properties and durability of still reproduction for a magnetic recording medium and at the same time removing the cylinder soil or the like, by adding the speific fatty acid compound and the specific diester compound into a magnetic layer.
CONSTITUTION: The compound of one or more kinds among the saturated and unsaturated fatty acids of C12W24 such as the lauryl acid, myristic acid or the like plus one or more kinds among the aliphatic dibasic acid ester compounds such as the ditetradecyl succinate or the like shown in the formula [R1 and R3 are alkyl groups of C10W26; R2 is (CH2)n, n=2W6 and (CH=CH)] are added into the magnetic layer of a magnetic recording medium such as a magnetic tape or the like by about 1W15pts.wt. to the 100pts.wt. magnetic substance. The mixing ratio is set to about 1:9W9:1 in terms of wt. between the both compounds. A surface smoothing treatment is given to the surface of the magnetic layer onto which the above- mentioned compounds are coated. Thus a magnetic recording medium is obtained with a high smoothness and high hardwearing properties.
