Magnetic recording medium |
| abstract |
A magnetic recording medium having high running stability and good magnetic characteristics without causing an abrasion problem, which comprises a base film, a magnetic layer provided on one surface (i.e. the major surface) of the base film and a back coat layer provided on the other surface (i.e. the back surface) of the base film, the back coat layer comprising a binder and non-magnetic particles dispersed therein, characterized in that the non-magnetic particles comprise at least one soft inorganic pigment having a hardness of less than 5 in Mohs' scale of hardness and at least one hard inorganic pigment of not less than 5 in Mohs' scale of hardness and of not more than 0.2 mu m in average particle size in a weight ratio of the soft pigment to the hard pigment of 99:1 to 50:50. |
