摘要：

A new structure for sputtered thin-film high-density longitudinal magnetic recording media using glass substrates has been proposed. The coercivity of Co alloy films is increased considerably by depositing a thin Ti layer between the Cr underlayer and the glass substrates. X-ray diffraction analysis indicates a change in the preferred orientation of the Cr layer. Transmission electron microscopy reveals that there is a significant change in the microstructure of the columnar Cr layer when Ti coating is used. It is proposed that the Ti film prevents oxygen from the glass substrates from reacting with the Cr and Co alloy magnetic layers.
