Abstract:
The magnetic tape device including: a magnetic tape including a servo pattern on a magnetic layer; and a TMR head as a servo head, in which a center line average surface roughness Ra measured regarding a surface of the magnetic layer of the magnetic tape is equal to or smaller than 2.0 nm, a logarithmic decrement acquired by a pendulum viscoelasticity test performed regarding the surface of the magnetic layer is equal to or smaller than 0.050, and ΔSFD in a longitudinal direction of the magnetic tape calculated by Expression 1: ΔSFD=SFD 25° C. −SFD −190° C.  is equal to or smaller than 0.50, wherein the SFD 25° C.  is SFD measured in a longitudinal direction of the magnetic tape at a temperature of 25° C., and the SFD −190° C.  is SFD measured in a longitudinal direction of the magnetic tape at a temperature of −190° C.

Claim (Index 6):
