摘要:
In a magnetic disk medium, a substrate is etched to have a designed, controlled topography. A magnetic recording medium and a protective layer are provided over the substrate. A method for controlling production of the surface characteristics of the magnetic disk medium is controlled to optimize surface characteristics for use of the magnetic disk medium in a magnetic disk apparatus that reads information stored on the magnetic disk medium.
摘要:
A disk medium includes a substrate and a designed topography of individually magnetizable features formed on the surface of the substrate. At least a portion of the topography is formed from an etched layer of magnetizable material deposited on the surface of the substrate. An information system records information on the disk medium magnetically and reads the recorded information optically or magnetically.

New Fischer-Tropsch catalysts containing a Lanthanide Group element, such as cerium, exhibit improved activity over conventional catalysts and exhibit a reversal in the olefin/paraffin ratio of low molecular weight hydrocarbons. The catalyst comprises:(a) a Group VIII metal oxide;(b) a Group IIB metal oxide;(c) a Group IVB and/or VIIB metal oxide;(d) a Group IA metal oxide; and,(e) a Lanthanide group metal oxide.

Presented are systems and methods to simultaneously produce and store energy in the form of chemical products such as hydrogen and other chemical products, thereby, reducing or eliminating the need to store energy in lithium-ion batteries. In various embodiments this is accomplished by converting energy from a renewable energy source to generate and accelerate an electron beam so as to generate electromagnetic radiation at frequencies equal to absorption frequencies of chemical reactants in order to produce the desired chemical products.

A disk medium includes a substrate and a designed topography of individually magnetizable features formed on the surface of the substrate. At least a portion of the disk topography is formed from an etched layer of magnetizable material deposited on the surface of the substrate. An information storing and retrieving system records information on the disk medium magnetically and reads the recorded information optically or magnetically. The information stored in the disk is of the form of bits each represented by a magnetic field established in the features. The direction of the magnetic field can be in a direction other than the bitstream direction, with the magnetic storing and retrieving system having a pair of non-parallel heads adapted to recognize this direction as representative of discrete logic levels formulating the basis of a non-binary storage system having significantly increased storage density.

摘要:
Chemical generator and method for generating a chemical species at a point of use such as the chamber of a reactor in which a workpiece such as a semiconductor wafer is to be processed. The species is generated by creating free radicals, and combining the free radicals to form the chemical species at the point of use.
