Magnetic recording medium and cartridge

Abstract

Provided is a magnetic recording medium capable of suppressing adhesion of a configuration material of a magnetic layer to a head during traveling. A magnetic recording medium is a magnetic recording medium in a tape shape, and includes a base and a magnetic layer. The magnetic recording medium contains a lubricant. The magnetic layer contains magnetic particles, a binder, and carbon. In a case where an average electron count rate of a surface of a standard sample measured by atmospheric photoelectron yield spectroscopy is A0, an average electron count rate of a surface of the magnetic layer measured by the atmospheric photoelectron yield spectroscopy before cleaning of the magnetic recording medium is A1, and an average electron count rate of the surface of the magnetic layer measured by the atmospheric photoelectron yield spectroscopy after cleaning of the magnetic recording medium is A2, ((A2/A0)−(A1/A0))/(A2/A0) satisfies 0.20≤((A2/A0)−(A1/A0))/(A2/A0)≤0.49.
