| titleOfInvention | Magnetic recording medium and cartridge |
| abstract | PROBLEM TO BE SOLVED: To provide a magnetic recording medium having both excellent running stability and electromagnetic conversion characteristics. In a recording / reproduction system, a magnetic tape MT is a tape-shaped magnetic recording medium, and includes a base 41, a base layer 42 provided on the base, and a magnetic layer 43 provided on the base layer. To be equipped. The substrate contains polyester, the base layer and the magnetic layer contain a lubricant, the magnetic layer has a surface provided with a large number of pores 43A, and the arithmetic average roughness Ra of the surface is 2.5 nm or less. The total BET specific surface area of the magnetic recording medium measured in a state where the magnetic recording medium is washed and dried is 3.5 m 2 / g or more and 7.0 m 2 / g or less, and the vertical of the magnetic layer. The square ratio in the direction is 65% or more, the average thickness of the magnetic layer is 80 nm or less, the average thickness of the magnetic recording medium is 5.6 μm or less, the servo pattern is recorded on the magnetic layer, and the servo is The statistical value σ SW indicating the non-linearity of the pattern is 24 nm or less.
