Magnetic recording medium |
abstract |
A magnetic recording medium comprising a non-magnetic support having provided thereon in this order, a first magnetic layer containing ferromagnetic particles dispersed in a binder and a second magnetic layer containing ferromagnetic particles dispersed in a binder, wherein said second magnetic layer contains particles of an abrasive material having a Mohs' hardness of 8 or more in an amount of 1 to 15 wt % based on the weight of the ferromagnetic particles contained in the second magnetic layer, said first magnetic contains particles of an abrasive material having a Mohs' hardness less than 8 in an amount of 5 to 50 wt % based on the weight of the ferromagnetic particles contained in the first magnetic layer, and the proportion of the abrasive material to the ferromagnetic particles in said first magnetic layer is larger than that in said second magnetic layer. |
