摘要： Producing magnetic-recording media includes providing a substrate and forming a plurality of functional layers over the substrate to provide a coated substrate adapted for recording. At least one of the layers of the magnetic-recording media is fluid jet printed as a printed layer. In some embodiments, the printed layer provides at least one of load-bearing functionality, head-cleaning functionality, adhesion-promoting functionality, reaction-promoting functionality, lubricating functionality, surface-cleansing functionality, magnetic-recording functionality, and edge-finishing functionality.

摘要： Magnetic storage media and methods for constructing magnetic storage media that include a multilayer structure are described. In general, the magnetic storage media include a substrate, an underlayer formed over the substrate, and a magnetic layer that includes a plurality of magnetic particles formed over the underlayer. In some examples, a magnetic recording medium can be formed by forming an underlayer over a substrate, drying the underlayer, and heat-curing the underlayer prior to forming a magnetic layer over the underlayer. A magnetic layer can then be formed over the underlayer. The magnetic layer may includes a plurality of magnetic particles selected from the group consisting of magnetic platelet-shaped particles and magnetic particles with an aspect ratio less than or equal to approximately 1.5, may then be formed over the underlayer. By heat-curing the underlayer prior to forming the magnetic layer over the underlayer, the formed magnetic recording medium may exhibit an improved magnetic recording surface for recording and storing data.

摘要： Magnetic storage media that include a multilayer structure are described. In general, the magnetic storage media include a substrate, an underlayer that includes a plurality of underlayer particles formed over the substrate, and a magnetic layer that includes a plurality of magnetic particles formed over the underlayer. The magnetic layer may define a saturated magnetization and thickness product less than or equal to approximately 1.00 memu per square centimeter, and the magnetic particles may be selected from the group consisting of magnetic platelet-shaped particles and magnetic particles with an aspect ratio less than or equal to approximately 1.5. In addition, the described magnetic storage media may exhibit minimal interlayer diffusion between the underlayer and magnetic layer. Reduced interlayer diffusion between different layers of a magnetic recording medium may result in an improved magnetic recording surface for recording and storing data.
