| titleOfInvention | Magnetic tape and magnetic tape device |
| abstract | PROBLEM TO BE SOLVED: To reduce the frequency of occurrence of signal defects in a timing-based servo system in a magnetic tape having a thin total thickness and improved surface smoothness of a magnetic layer. A magnetic tape having a magnetic layer containing a ferromagnetic powder and a binder on a non-magnetic support, the total thickness of the magnetic tape is 5.30 μm or less, and the magnetic layer has a timing-based servo pattern. The centerline average surface roughness Ra measured on the surface of the magnetic layer is 1.8 nm or less, the ferromagnetic powder is ferromagnetic hexagonal ferrite powder, the magnetic layer contains a polishing agent, and scanning transmission type electrons. A magnetic tape in which the inclination cosθ of the ferromagnetic hexagonal ferrite powder with respect to the surface of the magnetic layer determined by cross-sectional observation performed using a microscope is 0.85 or more and 1.00 or less. Magnetic tape device. [Selection diagram] None |
