A fault-tolerant distributed collaborative computer system is provided that comprises a plurality of server computers interconnected via a high-speed link. By replicating the conference information on more than one server computer, the single point of failure limitation is eliminated. In fact, if a server hosting or participating in a conference malfunctions, the failure is detected by other server computers and the client computer is able to reconnect to the conference through a new server computer. In addition, the state of processes executed by the server computers is periodically replicated, so that when failure of a process is detected a new processes can be spawned and the replicated state information loaded onto the new process, allowing the on-line conference to continue.

A distributed collaborative computer system is provided that comprises a plurality of server computers interconnected via a high-speed link. Client computers can connect to any available server computer and start or join a conference hosted on either the server computer to which the client computer is connected or any other server in the system. As a result, the system and method of the present invention is easily scalable to support an arbitrary number of participants to a conference by merely adding the appropriate number of server computers to the system. In addition, by replicating the conference information on more than one server computer, the single point of failure limitation is eliminated. In fact, if a server hosting or participating in a conference malfunctions, the failure is detected by other server computers and the client computer is able to reconnect to the conference through a new server computer.

A method and system for providing a magnetic structure in magnetic transducer is described. The method and system include providing a pinning layer, a synthetic antiferromagnetic (SAF) adjacent to the pinning layer, a nonmagnetic layer, and a sensor layer. The SAF resides between the nonmagnetic and pinning layers. The nonmagnetic layer is between the SAF and the sensor layer. The SAF includes a pinned layer, a reference layer, and a nonmagnetic spacer layer between the pinned and reference layers. The pinned layer is magnetically coupled with the reference layer and includes sublayers. A first sublayer has a first blocking temperature distribution (T) and a first exchange energy. A second sublayer has a second Tand a second exchange energy. The first sublayer is between the pinning layer and second sublayer. The first Tis greater than the second T.
