摘要： Beginning with a smooth ground aluminum blank with a relatively thin layer of leveled Ni—P, circumferential electropolishing/texturing is carried out to achieve a smooth oriented surface. A conductive slurry is provided between the disc and a porous texturing tape which is in contact with a conducting plate or equivalent conductor. The disc serves as the anode, and the conducting plate as the cathode, while the slurry, being conductive, functions as an electrolyte. In the presence of current, a reverse electroplating occurs so that the Ni—P dissolves to form Ni2+, or nickel ions which are carried away by the conductive slurry. The conductive slurry further supports or carries therein abrasive material so that by moving the porous texturing tape past the disc surface, the texturing tape picks up the abrasive material in the slurry and simultaneously with the reverse electroplating, provides the desired mechanical abrasion to achieve texturing of the disc surface. The abrasive material comprises diamond particles. The circumferential electropolishing/texturing polish is achieved by spinning the disc while applying the mechanical-chemical action through the slurry system to the disc surface with electric current passing through the electrically conducting interface during processing.

摘要： A method of manufacturing a magnetic recording medium comprises steps of providing a non-magnetic substrate having at least one surface; forming a layer of a sol-gel on the surface, partially drying the sol-gel layer at room temperature to remove a portion of the solvent therein to form a partially dried sol-gel layer of hardness less than that of the substrate; mechanically texturing the surface of the partially dried sol-gel layer; and depositing a layer stack including at least one magnetic layer thereover. Embodiments of the invention include embossing a servo pattern in the as-deposited sol-gel layer prior to partial drying and mechanically texturing, followed by sintering at an elevated temperature to form a substantially fully dried layer having a density and hardness similar to that of glass, and formation of a thin film magnetic media layer stack thereon.

摘要： A perpendicular magnetic media includes a substrate, a patterned template, a seed layer and a magnetic layer. The patterned template is formed on the substrate and includes a plurality of growth sites that are evenly spaced apart from each other. The seed layer is formed over the patterned template and the exposed areas of the substrate. Magnetic material is sputter deposited onto the seed layer with one grain of the magnetic material nucleated over each of the growth sites. The grain size distribution of the magnetic material is reduced by controlling the locations of the growth sites which optimizes the performance of the perpendicular magnetic media.

摘要： The present invention provides a method for detecting missing servo patterns on printed recording media. In general, the method first comprises the step of generating a map of anticipated servo burst patterns for a magnetic medium. The magnetic medium is typically a magnetic storage disc. Next, the magnetic medium is placed onto a disc reading assembly. Using the disc reading assembly, individual servo bursts on the magnetic medium are identified. In one embodiment, signals from the magnetic medium are processed through a frequency down conversion process, coupled with band pass filtering and rms-to-DC conversion. This enables higher throughput of signal processing. A map of identified servo bursts on the magnetic medium can then be generated. The map of identified servo bursts is then compared with the map of anticipated servo burst patterns. In this way, missing servo bursts can be detected.

摘要： Embodiments of the invention generally provide an electron beam substrate processing system. In one embodiment, the present invention provides an electron beam substrate processing system where a spindle shaft used to rotate substrates during processing includes two encoder wheels. One encoder wheel is configured to provide a rotational speed data signal to a rotational speed control system. Another encoder wheel is configured to provide a pattern generator clock signal at a higher frequency than the rotational speed data signal to a pattern generator. In one embodiment of the present invention, at least one of the encoder wheels is positioned adjacent the substrate to minimize torsional and differential movements between the at least one encoder wheel and the substrate.
