摘要： A magnetic recording medium is disclosed which is comprised of a non-magnetic support having a magnetic layer provided thereon. The magnetic layer is comprised of two different types of carbon black having different particle sizes, a lubricant which is liquid at room temperature, a ferromagnetic powder all dispersed in a binder. A carbon black (1) has an average particle size smaller than 50 m.mu. and a carbon black (2) has an average particle size of larger than 120 m.mu.. The carbon black is present in a weight ratio of (1)/(2) within the range of 50/50 to 97/3. The magnetic recording medium has improved electromagnetic properties and running durability. In addition, the material provides an improved S/N ratio and an improved coefficient of friction.

摘要： A method for producing a magnetic recording medium is disclosed. The method involves providing a ferromagnetic coating layer on a non-magnetic support base to produce a coated base. The coated base is then subjected to an atmosphere having a RH of 60% or more, prior to or during a subsequent calendering treatment. The recording medium produced has excellent surface smoothness and improved electromagnetic properties. The method is advantageous in that a substantially long period of time may pass between the coating of the ferromagnetic layer on the support and the calendering treatment without having undesirable effects on the magnetic recording medium produced.
