Methods and systems for obtaining the performance characteristics of a computing product are described. The computer program product is arranged to obtain sealing system component information items from a database, including: a sealing system component text information item; a duty level information item; a sealing system component graphic information item; and a rod end information item. The mobile terminal device comprises at least a IC tag data receiving section for receiving IC tag data from the IC tag reader-writer which reads the IC tag data out of the IC tag, and a server data request transmitting section for a data request signal to the server in order to request server data relative to the IC tag data. The embodiment further comprises a crowder configured to support the disc drive, wherein the crowder is disposed to oppose the driving force imparted to the disc drive by the actuator. The MFR can be doped with different types of tracers, thereby allowing placement of different tracers at several different positions upstream.
