| titleOfInvention | Magnetic recording medium, magnetic recording/reproducing device, and magnetic recording medium cartridge |
| abstract | Provided is a magnetic recording medium capable of exhibiting good traveling performance during use. This magnetic recording medium is a tape-shaped magnetic recording medium having: a substrate; an underlayer provided on the substrate; and a magnetic layer provided on the underlayer. The substrate includes polyester as a main component. The average thickness of the underlayer is 0.9 µm or less. The underlayer and the magnetic layer each include lubricant. The magnetic layer has a surface having multiple holes provided therein and the surface has an arithmetic average roughness Ra of 2.5 nm or less. The BET specific surface area of the entirety of the magnetic recording medium in a state where the lubricant is removed and dried is 3.5 m2/g or more. The squareness ratio in a perpendicular direction is 65% or more. The average thickness of the magnetic layer is 90 nm or less. The average thickness of the magnetic recording medium is 5.6 µm or less. |
