Abstract

PURPOSE: To prevent the occurrence of spacing between tape/head and prevent the decrease in video sensitivity and S/N by discretely providing lubricants on magnetic layer surface.
CONSTITUTION: A magnetic layer B is coated on a base C and after calender processing in succession or after the base is slit to tape or sheet form, the solution of a suitable lubricant A is discretely coated to a thickness 1μ or under, preferably 0.1μ or under. The measurement method thereof is converted by 100d/λ(dB). The degree of discreteness is such that the ratio S2/S1 of a surface area S2 on which the lubricant is coated with respect to the coating surface area S1 of the magnetic tape is made less than 0.8, preferably less than 0.5.
