A method of storing a data storage device includes but is not limited to emplacing a data storage device in a container, the container having surfaces; and writing storable data to the data storage device by transmitting energy through a surface of the container. The package also has a back portion with an area and an outer periphery. Destination identifiers that are included in first communications packets that are received by edge switches, which are connected directly to said host or directly connected to said IO adapter, are translated before routing the communications packets out of the edge switches. If the rate of attenuation loss indicates that a threshold insertion loss will be crossed before the next attenuation measurement, the splicing machine is stopped prior to the next attenuation measurement. In the magnetic recording and playback apparatus, data necessary for accessing to a magnetic tape and part of user data recorded on the magnetic tape are recorded at a predetermined position of the magnetic tape, and then the magnetic tape is discharged.
