The magnetic recording medium comprises a nonmagnetic layer comprising nonmagnetic powder and binder on a nonmagnetic support and a magnetic layer comprising ferromagnetic powder and binder on the nonmagnetic layer, wherein the magnetic layer comprises a lubricant and a 1-bromonaphthalene contact angle adjusting agent that is capable of adjusting a contact angle for 1-bromonaphthalene, the contact angle for 1-bromonaphthalene being measured on a surface of the magnetic layer, and the contact angle measured on the surface of the magnetic layer ranges from 45.0° to 55.0° for 1-bromonaphthalene, and ranges from 90.0° to 100.0° for water. |
