A display having improved thermal management and a method for producing the display are disclosed. The method comprises delivering electrical energy to a glia at a margin of the glioma, thereby stimulating the glioma. The particular compounds are generally polymeric in nature including various chain lengths of polyoxyalkylenes thereon and are liquid in nature to facilitate handling and introduction within the target media. If an indicator on the smartcard is set to \u201cupdate\u201d, the remote server then retrieves a backup card image that corresponds to the card from the card image server. A method for reading and writing data to a magnetic recording tape according to another embodiment includes simultaneously writing data tracks to a magnetic medium; and simultaneously reading the data tracks on the magnetic medium using a plurality of adjacent read devices; wherein the number of the adjacent read devices is at least twice the number of the adjacent write devices. The host device provides a key reference or ID, while the memory system generates a key value in response which is associated with the key ID, which is used as the handle through which the memory retains complete and exclusive control over the generation and use of the key value for cryptographic processes, while the host retains control of files.
