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.
摘要翻译：描述了磁存储介质和用于构造包括多层结构的磁存储介质的方法。通常，磁存储介质包括衬底，在衬底上形成的衬底，以及包括形成在衬底上的多个磁性颗粒的磁性层。在一些实例中，可以通过在衬底上形成底层，在底层上干燥底层和在底层上形成磁性层之前对底层进行热固化来形成磁记录介质。然后可以在底层上形成磁性层。磁性层可以包括选自磁性片状颗粒和纵横比小于或等于约1.5的磁性颗粒的多个磁性颗粒，然后可以在底层上形成。通过在将下一层形成磁性层之前对底层进行热固化，所形成的磁记录介质可以呈现用于记录和存储数据的改进的磁记录表面。

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.

摘要： Improvements in the attenuation of sounds emitted by an internal combustion engine exhaust system are achieved by shaping a muffler housing to substantially eliminate flat sound radiating surfaces, providing a circuitous exhaust gas flow path within the muffler housing and around an imperforate barrier and providing an exhaust gas outlet from the muffler housing which extends generally perpendicular to the direction of sound propagation within the housing near that outlet. The housing may be generally ellipsoidal in shape having a non-zero curvature which varys in a continuous manner at substantially all points on the surface and, subject to that requirement, designed to have a generally maximal volume subject to the dimensional constraints of its environment.
