Abstract: A process for simultaneously selectively depositing a high purity nickel containing alloy (i.e. a nickel-boron alloy having a nickel content in excess of 99.5 percent) over a preformed metallurgy pattern (including the individual, electrically isolated contact pads and the seal band area thereon) on the top-side dielectric surface of a multi-layer ceramic module. The metallurgy pattern on such top-side surface of such module is appropriately catalyzed and then immersed in a bath which is essentially lead-free and which includes a source of nickel ions, a borane reducing agent, and an effective amount of an organic divalent sulfur compound, preferably thiodiglycollic acid.

Abstract: Access time is improved in a automated library system having sequentially stored data on a recording tape medium. A multiplicity of copies of the data is stored on different tape cartridges. The copies and the original are stored in different areas of the library. Each data segment stored on the tape media copy is stored in different areas of the media length from the original. The multiple copies are created and deleted independent of any user control. The usage of the original and any copies determine the number of copies and their residence times. The library manager selects the tape cartridge that can be retrieved in the shortest response time using the location of the original and the copies, the location on each cartridge of the data requested, the drive and library robot picker availability and the respective queues.

Abstract: A system uses prevent and detect mechanisms to enable rewritable data storage media to be operated as a written-once-only media. A physical indication of the media casing serves as an indicator of the write-once-only status of the media. A watermark is magnetically recorded on the media at the factory with a portion of the mark detectable by the system and a portion only detectable by returning to an inspection station for verification. This protects against a complete erasure of all data from the media. A segment write status indication serves to indicate the write-once-only status of each segment of the written data. A portion of the written region, such as the preamble or control field of each segment, contains a status mark written randomly within the area as a status indication that the data was written once or multiple times within that segment.
