Abstract
There have been intensive research activities on perpendicular magnetic recording media using CoCrPt-SiO2 material as the recording layer. To obtain a relatively high coercivity and good crystallography relatively thick Ru thickness is necessary. In this paper, we studied the effect if NiCr and NiFeCr seedlayer on the magnetic properties and crystallography of CoCrPt-SiO2 PMR media using vibrating sample magnetometer and X-ray diffractometry (XRD). The PMR media were deposited by sputtering on a glass substrate.
