R. Taguchi et al., THE FABRICATION OF CO-CR-TA NI-FE DOUBLE-LAYER TAPE FOR A HIGH-DENSITY DIGITAL VTR/, Journal of magnetism and magnetic materials, 176(1), 1997, pp. 8-12
A Co-Cr-Ta/Ni-Fe double-layer tape was fabricated on 10 mu m-thick pol
yimide film by facing targets sputtering. The Co-Cr-Ta/Ni-Fe double-la
yer tape showed higher read/write performance than the Co-Cr-Ta single
-layer tape in not only the short but also the long wavelength region.
This suggests that the tape can be used for high-density recording in
a digital VTR.
