Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for storing, in an index associated with a document, a particular term that occurs in the document, wherein the particular term comprises n words, and wherein n is greater than 1; identifying a substitute term of the particular term; and in response to identifying the substitute term of the particular term, storing, in the index associated with the document, (i) the substitute term of the particular term, and (ii) data indicating that the substitute term spans the n words of the particular term.

Storing term substitution information in an index

Serving a search result is disclosed. A security fingerprint of a security configuration is generated. The security fingerprint is concatenated with a query having a search term and a search result is returned that includes both the search term and the security fingerprint.

Continuous security updates

Serving a search result that includes an access controlled document includes obtaining a persistent access token that permits the verification of access to an access controlled document. The access controlled document is found in an index that includes an access controlled document and the persistent access token is used to verify authorization to access the access controlled document.

Access controlled search results

A magnetic medium is formed with a barrier layer between the magnetic layer and protective overcoat to prevent degradation of magnetic properties during deposition of the protective overcoat due to poisoning effects by reactive gases on the magnetic layer. Embodiments include sputter depositing a Cr or Cr alloy barrier layer, having a thickness of about 5 &angst; to about 25 &angst;, on a magnetic layer and sputter depositing a protective overcoat containing carbon and nitrogen on the barrier layer in a nitrogen-containing environment.

Magnetic recording medium with protective barrier layer

Adhesion between a deposited seed layer, e.g., a sputter-deposited NiP seed layer, on an alternate substrate, such as a glass, ceramic or glass-ceramic substrate, is significantly enhanced by depositing a chromium or chromium-alloy adhesion enhancement film between the substrate and seed layer. Magnetic recording media comprising a surface-oxidized NiP seed layer and chromium adhesion enhancement film exhibit low media noise and are suitable for high density longitudinal magnetic recording.

Magnetic thin film medium with adhesion enhancement layer

Hydrogen-treated, sputter deposited, titanium nodules providing enhanced micro-texturing for thin film, magnetic, disk media.

Micro-texturing for sputtered, thin film magnetic media disks utilizing

An enhanced magnetic head is characterized by sputter induced, micro-texturing yielding rounded globular configurations on slider rail portions. Optimally, this enhanced head is employed in combination with sputter induced micro-textured thin film disk media having a surface or coarseness greater than that of the magnetic head.

Sputter induced micro-texturing enhancement for magnetic head structures

Sputter induced micro-texturing of thin film magnetic media discs entailing the formation of micro-texturing globules comprising a eutectic alloy of Indium and Bismuth.

Method of fabricating sputter induced, micro-texturing of thin film,

A magnetic thin film alloy comprising cobalt, chromium, nickel and platinum for horizontal recording has a high coercivity, good corrosion resistance, and good noise performance. The platinum has a concentration between 8 to 15 atomic percent, the chromium has a concentration of 3 to 8%, the nickel concentration is 5 to 10% and the balance consist of essentially cobalt. The magnetic alloy has a thickness less than 100 nm and is sputtered on an undercoat consisting of nickel and phosphorus. The phosphorus content is between 5 to 30 weight percent, and the nickel phosphorus has a thickness between 5 and 100 nm. Alternatively, other amorphous metallic thin film undercoats can be applied. By judicious selection of the amount of chromium and nickel in the alloy, the saturation magnetization can be kept high while still maintaining good corrosion resistance. In addition, the sputtered media exhibits low noise.
