A magnetic storage medium includes a magnetic storage medium that exhibits a magnetic compensation temperature specified higher than room temperature to minimize effects of heat generated by a head using magneto-resistance effect. One embodiment may be seen as instantiating a server in a container having instances of Enterprise Java\u2122 Beans, and accessing the EJB through the local interface of the EJB. Further, a light-emitting element having high emission efficiency has been able to be provided by use of the carbazole derivative. Next, the method determines a group of estimated information data in response to the first channel impulse response. Then, a topology of a virtual resource is constructed using a plurality of virtual resources that are in at least one of a defined, a created, or an instantiated state.
