Zusammenfassung:A limit stop for a magnetic storage system having a combination of visco elastic inner core and a thin walled outer shell enclosing the visco-elastic material, and a method of manufacturing the same. The thin wall is hermetically sealed to isolate the inner core material and eliminate the possibility of contamination to the disk drive interior. The visco-elastic inner core has the properties of very good energy dissipation, while the outer shell provides high dimensional control and stability.
