Magnetic tape 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,
• a center line average surface roughness Ra measured regarding a 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, and
• a tilt cos θ of the ferromagnetic hexagonal ferrite powder with respect to a surface of the magnetic layer acquired by cross section observation performed by using a scanning transmission electron microscope is 0.85 to 1.00.
