A failure-effect validation system includes an effects modeler configured to develop a cumulative effects model for failure modes of the complex system, and by which a model of the complex system is extendible to form an extended complex-system model. The actuator operates parallel to the axle to alleviate speed sensitivity. The conductive grid is aligned with an opening of the smart package. Identification information of a secondary recording medium or a playback apparatus is obtained according to whether the secondary recording medium is removable from the playback apparatus.
