Magnetic recording medium and magnetic recording and reproducing device

A magnetic recording and reproducing device comprising:

• a magnetic recording medium;
• and
• a magnetic head,
• wherein the magnetic recording medium is a magnetic recording medium comprising:
• a non-magnetic support;
• and
• a magnetic layer including a ferromagnetic powder and a binding agent,
• wherein the ferromagnetic powder is a ferromagnetic hexagonal ferrite powder,
• the magnetic layer includes an oxide abrasive,
• an intensity ratio Int(110)/Int(114) of a peak intensity Int(110) of a diffraction peak of a (110) plane with respect to a peak intensity Int(114) of a diffraction peak of a (114) plane of a hexagonal ferrite crystal structure obtained by an X-ray diffraction analysis of the magnetic layer by using an In-Plane method is 0.5 to 4.0,
• a vertical squareness ratio of the magnetic recording medium is 0.65 to 1.00,
• a contact angle with respect to 1-bromonaphthalene measured regarding a surface of the magnetic layer is 50.0° to 55.0°, and
• an average particle diameter of the oxide abrasive obtained from a secondary ion image obtained by irradiating the surface of the magnetic layer with a focused ion beam is 0.04 μm to 0.08 μm.
