  • Target, An Underlayer Material For Co-Based Or Fe-Based Magnetic Recording Media, And Magnetic Recording Media
    Publication number: 20130108890
    Abstract: The present invention is related to a target, which is a magnesium monoxide-based (MgO-based) composite having cubic crystal structure of MgO, wherein the MgO-based composite includes MgO and one or more oxides. Using MgO-based composite to form an underlayer material can improve the bonding strength among particles in the target, and then effectively reduce the falling of particles from the targets during sputtering. In addition, the MgO-based composite still maintains the cubic crystal structure of MgO, which is beneficial to make a MgO-based composites as an underlayer material in a magnetic recording medium. The invention is also related to an underlayer material for cobalt-based (Co-based) or iron-based (Fe-based) magnetic recording media. The invention is further related to a magnetic recording medium.
