With the evolution of magnetic tape to the Giga-byte level, smoother surface is required than before. The surface of the magnetic tape is smoothed in calendering process. It is necessary to estimate the surface roughness in the operation conditions of calender. This paper presents the analyzing method of the surface smoothing considering with the real contact area and the viscoelasticity of the magnetic layer at the temperature of calender roll. The calculated surface roughness is almost equal to experimental. However, in the case of soft calendering, calculated surface roughness is smaller than experimental. This is thought to be due to the visco-elastic deformation of the magnetic layer at the real temperature different from that of calender roll.
