DISK DAMPER AND HARD DISK DRIVE HAVING THE SAME

摘要

A disc damper and an HDD(Hard Disc Drive) with the same are provided to consistently reduce the vibration of a disc and an HSA(Head Stack Assembly) in a certain position from an inner diameter of the disc to an outer diameter of the disc. A disc damper includes a tailing part(124) and an expanding part(126). The tailing part(124) has a surface faced to data tracks of an outer diameter side of a disc. The expanding part(126) is connected with the tailing part(124), and is expanded to have a width which is broader than a radius direction width of the tailing part(124). The expanding part(126) has a surface faced to all data tracks of the disc.
