Magnetic recording medium and cartridge

Abstract

Provided is a magnetic recording medium capable of improving SNR even in a case where a crystallite volume of a magnetic powder is 1300 nm3 or less. The magnetic recording medium is a tape-shaped magnetic recording medium, and includes a substrate and a magnetic layer containing a magnetic powder. The magnetic powder contains hexagonal ferrite particles containing strontium. A crystallite volume of the magnetic powder as determined by X-ray diffraction is 1300 nm3 or less. An SFD curve of the magnetic layer is separated into a first peak and a second peak and a peak top of the second peak is located on a higher magnetic field side than a peak top of the first peak. A peak top position of the first peak is 1000 Oe or more and a standard deviation of the first peak is 1950 Oe or less. A peak top position of the second peak is 2800 Oe or more and 3900 Oe or less and a standard deviation of the second peak is 1400 Oe or less.
