Magnetic tape, magnetic tape cartridge, and magnetic tape apparatus

Abstract

The magnetic tape includes a non-magnetic support, and a magnetic layer containing a ferromagnetic powder. A magnetic tape cartridge and a magnetic tape apparatus include the magnetic tape. Svi obtained by measuring a surface of the magnetic layer with an atomic force microscope and by Equation A is 0.080 or more and 0.130 or less, and standard deviation σ of the Svi in a width direction of the surface of the magnetic layer is 0.010 or less. In Equation A, Sq is a root-mean-square height Sq specified in ISO 25178, Vv(h0.8) is a void volume in a region where a load area ratio in a bearing curve is 80% or more and 100% or less, and A is a measurement region area. Svi = ( Vv ⁡ ( h 0.8 ) A ) / Sq Equation ⁢ A
