Abstract: PROBLEM TO BE SOLVED: To provide a method and system for accessing distributed data. SOLUTION: The system includes a first entity (201-203) storing client data (221-223), the first entity requiring access information (220) to access the client data (221-223). A storage device (200) is held by the client and provides the access information (220) to access the client data (221-223). A second entity (204) is capable of accessing the stored client data (221-223) from the first entity (201-203) when provided with the access information (220) from the client.

Abstract: A thin film metal alloy magnetic recording disk has a protective nitrogen-containing carbon overcoat which is thinner and which exhibits better wear resistance, corrosion resistance, and hardness than conventional carbon overcoats without nitrogen. The nitrogen present in the disk overcoat substantially reduces the film stress. Because of the low stress of the overcoat film there is significantly less likelihood that the overcoat will delaminate, buckle, or otherwise wear away from the underlying magnetic layer during operation of the disk file. This allows for significantly reduced overcoat thickness, thus reducing the head-disk spacing in the disk file. The overcoat, even though significantly thinner than prior art carbon overcoats, exhibits better wear and corrosion resistance than carbon overcoats without nitrogen. In addition, when the carbon overcoat contains hydrogen, the presence of the nitrogen increases the hardness of the film if present in a specific amount dependent on the amount of hydrogen present.
