Abstract: Apparatus for connecting data processing equipment to a communications network includes hardware for a range of different communications standards. Also included is a coupler (preferably in the form of a cable) having a particular standard communications plug which contains an identifying code associated with that particular standard plug, which code is used to configure the apparatus to that particular standard. The apparatus contains a digital signal processor controlled by control code contained in a control store having associated therewith a standard identifier code. Control logic reads the standard identifier code associated with the control code and the standard identifying code in the coupler and enables the apparatus if the two match (or disables if they do not match).

Abstract: The sputter deposition of a thin film of material on both sides of a thin substrate is performed by positioning the substrate sides orthogonal to the target and preferably radial to the deposition center of the sputter system. The vapor deposition of alumina on a thin ferrite core for a magnetic head is accomplished by positioning the ferrite substrate in the vacuum chamber orthogonally to the target and radial to the particle deposition center. The alumina is deposited on both sides of the ferrite core simultaneously to substantially the same thickness. The deposition on both sides of the ferrite core protects the core against width erosion, and minimizes bending stress. In addition, signal output of the ferrite core when used in a magnetic head is increased.
