Magnetic tape having characterized magnetic particles and magnetic tape device

A magnetic tape device comprising:

• a magnetic tape,
• a magnetic head;
• and
• a servo head, wherein
• the magnetic tape is a magnetic tape comprising:
• a non-magnetic support;
• and
• a magnetic layer including ferromagnetic powder and a binder on the non-magnetic support,
• wherein the total thickness of the magnetic tape is equal to or smaller than 5.30 μm,
• the magnetic layer includes a timing-based servo pattern,
• the center line average surface roughness Ra measured regarding the surface of the magnetic layer is equal to or smaller than 1.8 nm,
• the ferromagnetic powder is ferromagnetic hexagonal ferrite powder,
• the magnetic layer includes an abrasive,
• the tilt cos θ of the ferromagnetic hexagonal ferrite powder with respect to the surface of the magnetic layer acquired by cross section observation performed by using a scanning transmission electron microscope is 0.85 to 1.00, and
• the percentage of hexagonal ferrite particles having a length in the long axis direction of equal to or greater than 10 nm and having an aspect ratio in a range of 1.5 to 6.0 in all of the hexagonal ferrite particles is equal to or greater than 50% but equal to or smaller than 95%, based on the particle number.
