A Co-Cr-Ta/Ni-Fe double layer tape was fabricated on 10μm thick polyimid film by facing targets sputtering system. The Co-Cr-Ta/Ni-Fe double layer tape showed higher read/write performance than the Co-Cr-Ta single layer tape in not only short wavelength region but also long wavelength region. It suggested that this tape is capable of high recording density of digital VTR.
