Piezo-remanent magnetization of various magnetic tapes was studied for the application to magnetic contact printing. Experimentally it was found that Co-γFe₂O₃ tape is most suitable for the slave tape. It was also concluded that the origin of piezo-remanent magnetization effect of Co-γFe₂O₃ tape is due to the inverse effect of magnetostriction, dispersion of Co atoms to vacant lattices and crystalline anisotropy. The initial piezo-remanent magnetic susceptibility of acicular Co-γFe₂O₃ tape used in this study was about one-sixth of the initial anhysteretic remanent magnetic susceptibility, and about one-fourth of that by the superposition of heat energy of 100℃.
