Abstract: A composite type thin-film magnetic head. In one embodiment, a substrate is used as a base, and an insulating film, a lower shielding magnetic film, a magneto-resistive element, an upper shielding magnetic film, a magnetic gap film, a recording inductive magnetic film and a protective layer are laminated on this base. An inductive head used for recording is formed by the upper shielding magnetic film. A magnetic gap film, a recording inductive magnetic film, and a magneto-resistive head used for playback are formed by the magneto-resistive element. The upper shielding magnetic film and recording inductive magnetic film are formed by an electroplating of permalloy. The upper shielding magnetic film has a lower nickel concentration on the side of the magnetic gap film than on the side of the magneto-resistive element.

Abstract: A method of managing access to a distributive network provides both time and site access restraints for users or groups of users on a LAN or WAN adapted for accessing the network through a common network access interface system. The method utilizes the LAN server to develop and monitor the constraints, minimizing the utilization of the access interface system. The management parameters for each group or individual having access to the distributive network via the LAN or WAN is entered into the interface box by the administrator as a compact reference, a series of pointers to the larger database of users and groups stored in the existing LAN server directory services. The existing database of users and groups and their relationships exist already in the LAN servers as a normal consequence of LAN operation and a simple, graphical user interface in the preferred embodiment of the invention permits familiar selection of objects of that database and assignment of access constraints.
