Abstract:In recent storage boxes, fan vibrations have become a major vibration source because of increasing processing power and storage capacity. The fan vibration causes high frequency vibration up to 10 kHz in the head positioning error (PES) of HDDs, and the FEM simulation method for them have been required from the viewpoint of the HDD developments. In this paper, we conducted PES simulation by using rigid-body accelerations as the input, which were measured by using a surrogate drive. The surrogate drive has six … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
