An agile digital communications network has a number of routers that serve as nodes in a mesh network communicating between a user device (e.g., computer, server, etc.) and a target device (e.g., disc storage cabinets, tape, jukebox, etc.). The routers operate on an open shortest path first protocol, each router having two or more interfaces or links to other routers. When a link connected to a router is down and is in the shortest path to another router identified in a communication packet, the packet is forwarded to the identified router on a precalculated alternate route that does not use the unavailable link. IP tunneling assures that routing loops do not occur and send the packet back to the router with the unavailable link because it would have been in the shortest path of an intermediate router. A tunneling technique is provided that maximizes the levels of encapsulation needed at two, regardless of the size or configuration of the network. An unavailable link is not broadcast immediately throughout the network, giving the link an opportunity to be restored before all of the routers are called on to recalculate the shortest paths and alternate paths. During a short interval following the discovery of an unavailable link, then, a router connected to that link is in a state identified as the Use Alternate Path state, and the link is repeatedly checked for availability. Each router calculates and stores the alternative paths to each other router after first calculating the shortest path to each other router. The alternate paths are pulled up and used when an unavailable link is detected. Dijkstra's algorithm is used to calculate the shortest paths. A new algorithm called the iterative dynamic Dijkstra's algorithm is used to calculate the alternative routes.

The preferable proportion displaying the desired optical characteristic is calculated based on the actual measurement value.

An apparatus and a method capable of efficiently and accurately constructing an access control configuration having high security are realized. Only the MAC address of a controller (client) 351 authorized by a user is authenticated and registered in a MAC address table of a device 352, and the device 352 performs MAC address filtering for permitting access by the controller 351 (client) which is authenticated and registered in the MAC address table. Furthermore, by making a registration completion notification and by performing version adjustment, a reliable access control configuration is constructed. The device authentication apparatus 350 avoids access from an unauthorized party which is not authenticated and registered, and makes the presence of a server not known to the controller which attempts to illegally perform device authentication. Therefore, access control with high security is realized.

A thermal component is mounted on the front surface of an isolator sheet within a first specific area. A thermally-conductive material is located on the back surface of the isolator sheet on the back of the first specific area. An electrically-conductive material is located on the front surface of the isolator sheet within a second specific area. A thermally-insulating material is located on the back surface of the isolator sheet on the back of the second specific area. The flexible printed circuit board unit of this type allows heat of the thermal component to efficiently radiate from the thermally-conductive material. An increase in temperature can be suppressed in the thermal component. Heat can reliably stay in the electrically-conductive material when a solder material is applied to the surface of the electrically-conductive material. The solder material is allowed to reliably fuse.

A connector is mounted on a printed circuit board in an enclosure. A member is interposed between the enclosure and the printed circuit board so as to hold the printed circuit board on the enclosure. The member allows change in the attitude of the printed circuit board relative to the enclosure. When the connector is coupled to the other connector, the connector receives a force from the other connector in the electronic apparatus. The force induces the change in the attitude of the connector and the printed circuit board. The change in the attitude in this manner enables consumption of the energy of the force within the member. Generation of stress can be suppressed in a bonding member such as a solder coupling the connector with the printed circuit board, for example. Generation of cracks can be prevented in the solder. Shockproof is improved for the connector.

When wire-bonding process is effected, a head assembly is held between a pair of clamp members. A head slider is urged against a microactuator. The urging force is transmitted to the microactuator through second adhesive layers. Since the second adhesive layers are positioned symmetrically around the rotational axis of the head slider, the urging force tends to act along the rotational axis. The microactuator is simultaneously urged against the support member. The urging force is transmitted from a first adhesive layer to the support member. Since the first adhesive layer extends around the rotational axis, the urging force tends to act along the rotational axis. The head slider is thus allowed to keep a uniform attitude. The microactuator is also allowed to keep a uniform attitude. The microactuator is prevented from suffering from substantial bending stresses.

The upper portion of a magnetoresistive film is interposed between insulators in the lateral direction of a recording track in a current-perpendicular-to-the-plane structure magnetoresistive element. Domain control magnetic layers sandwich the upper portion of the magnetoresistive film along with the insulators in the lateral direction. The insulators serve to establish a narrower path for electric current between the lower portion of the magnetoresistive film and an upper electrode layer. The substantial width in the lateral direction can thus be reduced in the magnetoresistive film. In addition, a longitudinal biasing magnetic field established between the domain control magnetic layers efficiently acts on the magnetoresistive film. In particular, if a free magnetic layer is included in the upper portion of the magnetoresistive film, the free magnetic layer can be subjected to a larger longitudinal biasing magnetic field. A single domain property can be realized in the free ferromagnetic layer enough. The Barkhausen noise can be reduced.

First magnetic crystalline grains are located at spaced positions on the surface of a base layer in a polycrystalline structure film. Magnetic interaction can reliably be prevented between the adjacent first magnetic crystalline grains. An amorphous material or a non-magnetic material covers over the first magnetic crystalline grains. An orientation controlling layer covering over the first magnetic crystalline grains and the amorphous or non-magnetic material on the base layer. Second magnetic crystalline grains are located at spaced locations on the surface of the orientation controlling layer. The orientation controlling layer serves to set the orientation in a predetermined direction in the second magnetic crystalline grains. Since the orientation of the magnetic crystalline grains can be aligned in a predetermined direction, the magnetic field of a sufficient intensity can be leaked out of the polycrystalline structure film.
