摘要： The present invention automates the publishing of financial, legal, and governmental documents and any other publications that are structured and require compliance with corporate or external standards and may share content elements. It gives users control in an always-on, familiar environment: the Internet. Due to its virtual document architecture and ability to operate over the Internet and intranets, the system facilitates collaborative work and traces accountability. The key concept behind automating publishing is to control scheduling and costs by better content management. The present invention handles document content as small, reusable components, down to the paragraph and table cell level. The interface helps users assemble documents from these version-controlled components with automated support. The system applies context and filtering criteria stored with each component to locate and apply content fragments to a current document. The system of the present invention can apply structural rules and content requirements to ensure compliance with regulatory requirements and company business rules. A working virtual document within the system always incorporates the current version of all constituent elements.

摘要： An interconnect between the write driver and the write head in a magnetic recording disk drive enables an inherent write current overshoot. The interconnect includes an integrated lead suspension (ILS) and a short flex cable that connects the write driver circuitry to the ILS. The interconnect is a two-segment transmission line, with the first segment connected to the write driver having multiple sub-segments or sections with non-uniform impedance levels. The section of the first segment that connects to the write driver is the short flex cable and has an impedance substantially higher than the source impedance ZWD of the write driver. The multiple sections of the first segment have non-uniform impedance values that have an effective impedance Z01-eff that substantially matches ZWD. The second segment of the transmission line has an effective impedance Z02-eff that is substantially less than Z01-eff. The write lines for the +W and −W signals are preferably interleaved on the transmission line sections.

摘要： A method for selectively choosing the magnetic properties of a sputter deposited recording layer of a magnetic recording medium comprises sputtering a target of metal underlayer material onto a substrate to deposit an underlayer film and selectively collimating the sputtered underlayer particles to vary the arrival energy and angular distribution of the sputter particles striking the substrate to selectively establish the orientation of the crystals making up the underlayer film. A magnetic metal film is then sputter deposited upon the underlayer film to form a magnetic recording layer, the magnetic metal film having a crystal texture and recording properties affected by the orientation of the crystals in the underlayer film. The magnetic properties of the magnetic recording layer are chosen by selectively collimating while sputter depositing the underlayer material. In an alternative embodiment of the present invention, both the underlayer film and the magnetic metal recording film are selectively collimated when deposited upon the substrate. A still further embodiment of the invention includes selectively collimating only the magnetic metal recording film.
