Magnetic recording medium and cartridge

Abstract

Provided is a magnetic recording medium that is capable of increasing the reproduction output. A magnetic recording medium is a tape-shaped magnetic recording medium and includes a recording layer. A nucleation magnetic field Hn of the magnetic recording medium satisfies a relationship of Hn≥0 [Oe], and the magnetic recording medium satisfies a relationship of the following formula (1). ( Mrt ) 0.5 × f ⁡ ( Hs ) ≥ 0.7 ( 1 ) (wherein, in the formula (1), Mrt represents a product of a residual magnetization amount Mr of the magnetic recording medium and a thickness t of the recording layer. Hs represents a saturation magnetic field of the magnetic recording medium. In a case where Hs≤8500 [Oe], f(Hs)=1.00, and in a case where Hs>8500 [Oe], f(Hs)=1/(1+(Hs−8500)/8500).).
