Abstract:
The magnetic tape device includes a magnetic tape; and a TMR head as a reproducing 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, in Expression 1, the SFD 25° C.  is a switching field distribution SFD measured in a longitudinal direction of the magnetic tape at a temperature of 25° C., and the SFD −190° C.  is a switching field distribution SFD measured in a longitudinal direction of the magnetic tape at a temperature of −190° C.

Claim (Index 12):
The magnetic reproducing method according to  claim 10 ,\n wherein the center line average surface roughness Ra measured regarding the surface of the magnetic layer is 1.2 nm to 2.0 nm.
