Abstract
PURPOSE: To prevent the coloring phenomenon of the magnetic head surface, by containing the inorganic particles where the surface of particles is formed with the edge of an acute angle and the average particle diameter is given within specific range, in the magnetic layer of magnetic recording medium.
CONSTITUTION: In the magnetic layer of magnetic recording medium, the inorganic particles, in which the average particle diameter is about 1W3μm, the edge of an angle is formed on the surface of particles, and Mohs hardness is preferrably about ≥ 6, are included by about 2W20 wt.%. Thus, when the magnetic tape is loaded to the magnetic recording and reproducing unit and run, the coloring of magnetic head surface can be avoided, the surface of magnetic layer is smooth, dropout is less, and further, the magnetic characteristics such as maximum magnetic flux density can be improved.
