Abstract

PURPOSE: To make it possible to remove alien substances stuck to a head without wear and damage of the magnetic head, by allowing to contain a specific quantity of nonmagnetic powder of a specific grading and stiffness for the total quantity of a filler and by giving a specific coating film surface roughness.
CONSTITUTION: Granular nonmagnetic powder of grain sizes of 0.2W2.0μ and a Mohs hardness below 9 is used as polishing grains, and 10W40wt% of this powder is allowed to contain for the total quantity of magnetic powder, needle-shaped nonmagnetic powder, and a filler such as carbon black, and these composites are mixed and dispersed by ball mill, etc., and are applied onto the substrate such as polyester film and are dried to form a polishing coating film. This film is formed by the calendar processing, etc., so that the surface roughness of the coating film may be center line average roughness 0.04W0.10μ. Thus, only alien substances stuck to the head can be removed without wear and damage of the magnetic head.
