Thin metallic films are the first choice for media in advanced rigid disk systems. For helical scan tape recorders thin metal films have become more important. The high signal-to-noise ratio per unit of track width allows very high densities.The preparation techniques and materials properties of the thin-film coating of metal evaporated (ME) are described. Important aspects are the size of the grains, the geometry of the columnar structure and the associated anisotropy. The consequences for the recording process are explained. Tribological and corrosion properties also help to determine the usefulness of a recording tape. Corrosion, wear, protection layers and lubricating organic films are briefly discussed.

“…eel temperature of CoO, the hysteresis loop shows a shift to lower fields a result of field cooling. The shift in the hysteresis loop is characterized by an exchange field H E ¼ 2000 Oe at 10 K. The previously observed [14] exchange bias confirms the presence of an antiferromagnet oxide.…”

“…When the films are cooled in the presence of a magnetic field, the interaction between the two phases gives rise to exchange anisotropy, which results in shifted hysteresis loops. In previous publications, we observed this feature in Co-Ni-O ME films [4]. The same occurs also in Co-O, and at an even larger extent.…”
