摘要：

An investigation was made into material concentration of magnetic media used in hard disks to obtain higher coercivity. It was found that a slight addition of element B in the magnetic layer of already known CoCrPt/Cr media could increase the coercivity significantly to 3000 Oe or more. X-ray diffraction analysis indicates that coercivity increase by added B element is caused by an intensified fct(111) phase in Co(CrPtB) in the magnetic layer.
