Abstract: A client program in a client/server relationship receives commands creating a specific implementation of graphical user interface (GUI) components and receives any data to be displayed in the interface components from the server program. As the end user interacts with the client, the client returns events and data to the server for processing. The commands and events constitute a protocol, published via an API. The transmission of commands events between the client and server is accomplished without linking the programs. The specific GUI implementation is specified by the server application and revealed to the client only at run time.

Abstract: A magnetic head includes aligned pole tips and a coil proximally disposed between a pair of first and second magnetic yoke layers which define a closed magnetic path with a transducing gap. The second magnetic yoke layer includes a flat geometry with a substantially level cross-sectional profile. The second yoke layer with less curvature results in less mutual inductance with the coil. Furthermore, the coil can be closely positioned between the first and second yoke layer, thereby allowing the coil to be more efficient in inducing magnetic flux in the yoke layers during data writing, and allowing the intercepted flux to induce current into the coil during data reading if the magnetic head is used as an inductive head.
