In this study, we investigate the dynamic characteristics of a cold-rolled steel-plate (SPCC) stamped base for use with a 2.5-in hard disk drive (HDD). A stamped base offers the advantages of a thinner form and lower manufacturing cost compared to die-cast bases. The feasibility of applying a stamped base to a 2.5-in HDD is investigated by considering the various required characteristics. The manufacturing processes for stamped and die-cast bases are compared, revealing several advantages of… CONTINUE READING
