sam Magnetic disk and method of manufacturing the same By www.freepatentsonline.com Published On :: Tue, 14 Apr 2015 08:00:00 EDT Provided is a magnetic disk that is excellent in durability, particularly in LUL durability and CFT properties, and thus has high reliability despite the low flying height of a magnetic head following the rapid increase in recording density in recent years and despite the very strict environmental resistance following the diversification of applications. A magnetic disk (10) has at least a magnetic layer (6), a carbon-based protective layer (7), and a lubricating layer (8) provided in this order over a substrate (1). The lubricating layer (8) contains a compound having a perfluoropolyether main chain in a structure thereof and having a polar group other than at ends of a molecule thereof. Full Article
sam Molybdenum dialkyldithiocarbamate compositions and lubricating compositions containing the same By www.freepatentsonline.com Published On :: Tue, 21 Apr 2015 08:00:00 EDT A novel molybdenum dithiocarbamate composition is produced by preparing a di-tridecylamine (DTDA) intermediate from a butylene feedstock comprising greater than 50% 2-butylene, and preparing a molybdenum dithiocarbamate composition from the DTDA intermediate. The resulting molybdenum dithiocarbamate composition are according to formula (1), wherein R1 to R4 are C11-C14 isoalkyl groups, and X represents oxygen and/or sulfur atoms, and R1 to R4 comprise, on average, greater than 98% C13: Full Article
