    Abstract: A method of manufacturing a magnetic recording medium comprises steps of providing a non-magnetic substrate for a magnetic recording medium, the substrate including at least one major surface; forming a layer of a sol-gel on the at least one major surface; forming a pattern, e.g., a servo pattern in an exposed surface of the layer of said sol-gel; and converting the layer of sol-gel to a glass or glass-like layer while preserving the pattern in an exposed surface of said glass or glass-like layer. Embodiments of the invention include magnetic media including a patterned glass or glass-like layer formed from a layer of a hydrophilic sol-gel with the pattern embossed therein by means of a stamper having a hydrophilic surface including a negative image of the pattern.

    Abstract: A specular reflecting layer is employed only one side of an AP pinned layer since a ruthenium (Ru) spacer layer in the AP pinned layer blocks conduction electrons. On the same side of the AP pinned layer a second pinned layer may be employed. With this arrangement the specular reflection layer reflects conduction electrons for enhancing a giant magnetoresistive (GMR) effect.

    Abstract: A gas sensor element includes a solid electrolyte layer having a plurality of projections formed on its outer surface, an inner electrode formed on the inner surface of the solid electrolyte layer, an outer electrode formed on the outer surface of the solid electrolyte layer, an outer electrode formed on the outer surface of the solid electrolyte layer and a spinel protection layer formed on the outer electrode for protection. The projections are formed on the outer surface of the solid electrolyte layer such that they are formed in a single layer; an area occupied by the projections accounts for 10% to 85% of the outer surface of the solid electrolyte layer and the distance between the neighboring projections is 5 &mgr;m to 300 &mgr;m. Thus, the outer electrode is formed on the solid electrolyte layer in such a manner as to penetrate into pits formed between neighboring projections and is thus strongly bonded to the solid electrolyte layer, thereby improving thermal durability. Also, since pores are hardly formed or are not formed at all between projections, a strong bond is established among the solid electrolyte layer, the outer electrode, and the protection layer, thereby improving durability against high temperature and high humidity.

    Abstract: A high quality metallic deposit can be produced inside the micro-cavities formed on a surface of a substrate by the present invention. The method involves immersing the substrate in a liquid held in a processing chamber, evacuating the processing chamber so as to remove residual bubbles from the micro-cavities and to degas the liquid within the micro-cavities, and subjecting the liquid to boiling in at least those regions adjacent to the substrate.

    Abstract: A method is provided for coating one or more fluid layers on a substrate to form magnetic recording media such as magnetic tape and diskettes. The method takes advantage of fluid coating formulations having a particular rheology that enables the coating of one or more magnetic layers with reduced thicknesses while achieving increased coating speeds. With proper rheology, one or more layers can be coated on a substrate traveling at increased speeds while maintaining desired coating thicknesses.
