摘要： Magnetic recording media exhibiting improved Hr, SNR and S*, suitable for high areal recording density, are obtained by forming a substantially uniform patterned Al or Al alloy layer on a non-magnetic substrate which is substantially replicated in subsequently applied layers to form a data zone. Embodiments include sputtering depositing an Al or Al alloy layer on the substrate and anodizing the sputtered layer to form a plurality of substantially uniform hexagonal cells comprising aluminum oxide. The hexagonal pattern is replicated in a subsequently deposited and epitaxially grown magnetic layer such that the magnetic grains are separated, thereby reducing magnetostatic interactions therebetween.

摘要： A magnetic recording medium having a substrate and a SiO2-containing magnetic layer comprising grains is disclosed. The magnetic layer has substantial SiO2 between the grains. This condition is achieved by sputter depositing the magnetic layer in a chamber containing a gas under vacuum. The gas contains substantially no oxygen. Such a gas is one into which no oxygen is intentionally introduced to create an oxygen-containing gas mixture but may contain a trace amount of oxygen molecules in an amount that are present in air under a similar vacuum as that of the gas in the chamber.

摘要： A magnetic recording medium exhibiting high remanent coercivity and low noise is produced by depositing a first NiAl seedlayer on a non-magnetic substrate, e.g., glass, ceramic or glass-ceramic material, at a relatively low temperature, and subsequently depositing a second NiAl seedlayer on the first seedlayer at a relatively higher temperature. Embodiments include depositing a first NiAl seedlayer at a temperature less than about 120.degree. C., e.g., less than about 100.degree. C., and depositing a second NiAl seedlayer thereon at a temperature greater than about 200.degree. C., e.g. greater than about 230.degree. C. Embodiments also include depositing a Cr-alloy underlayer, CrV, on the second seedlayer.
