摘要： Embodiments of the present invention provide solutions in the form of reducing the head to keeper spacing in a double-layered perpendicular magnetic recording medium, and improving the recording performance of the magnetic recording medium. A double-layered perpendicular magnetic recording medium and a method of fabricating the same are provided, for data storage devices and systems. The medium includes a base structure and a seedlayer disposed on the base structure. Further layers sequentially formed above the base structure are a soft magnetic underlayer, an intermediate layer and a magnetic recording layer. Because the soft magnetic underlayer is formed between the seedlayer and the intermediate layer, the seedlayer is excluded from the distance between the soft magnetic underlayer and the magnetic recording layer. The soft magnetic underlayer is therefore brought closer to the magnetic recording layer, providing a narrowed head-to-keeper spacing in a data storage system.

摘要： A method is provided to fabricate a magnetic recording medium which has a magnetic recording layer with reduced grain size. Prior to forming the magnetic recording layer, an intermediate layer is firstly formed, with a boundary phase surrounding and isolating the grains in the intermediate layer. With the formation of the boundary phase, the grain size of the intermediate layer can be successfully reduced. A magnetic recording medium includes an intermediate layer and a magnetic recording layer formed on the intermediate layer. In the intermediate layer, there is formed of segregate grains and a boundary phase which surrounds and isolates the grains, The magnetic layer has magnetic grains formed following the structure of the intermediate layer. The magnetic layer therefore has a relatively smaller grain size than that of conventional medium.
