Field of the Invention
The present invention relates to a magnetic recording medium, a magnetic signal reproduction device and a method of manufacturing a magnetic recording medium.
Discussion of the Background
In a particulate magnetic recording medium, a magnetic layer containing ferromagnetic powder and binder is present on a nonmagnetic support and a nonmagnetic layer containing nonmagnetic powder and binder is optionally present between the nonmagnetic support and the magnetic layer.
Conventionally, nonmagnetic powder (nonmagnetic particles) that can contribute to reducing the coefficient of friction during running has been incorporated along with ferromagnetic powder into the magnetic layer of a particulate magnetic recording medium (for example, see Japanese Unexamined Patent Publication (KOKAI) No. 2011-48878 or English language family members US2011/052908A1 and U.S. Pat. No. 8,535,817, which are expressly incorporated herein by reference in their entirety.
