摘要： A magnetic recording medium deposited on glass and having an orientation ratio greater than one is disclosed. The magnetic recording medium includes a CoW seedlayer deposited on a circumferentially textured glass substrate. The magnetic recording medium with such a seedlayer can have an OR that is similar or higher than that with a NiP seedlayer. Magnetic recording medium with a CoW seedlayer can produce oriented glass media with orientation ratio OR>1 when sputtered on substrates which have been circumferentially textured before the deposition of the CoW seedlayer. The W content of the CoW seedlayer can range between 30-50 at %. The thickness of the CoW seedlayer can range between 10 Å and 200 Å. The method for sputter depositing the magnetic recording medium is also disclosed and includes sputter depositing the CoW seedlayer using pure Ar as sputtering gas or using a mixture of Ar and O2, H2O and N2 as sputtering gas.
