Murata shock sensors find use in many computer hard disk drives. They detect impacts - for example, when the storage falls to the floor - in a fraction of a second and prevent read and write errors. Hard disk drives are fitted with 2 additional shock sensors positioned diagonally (acceleration sensors). The difference in the acceleration levels registered by both sensors is used to control rotational vibration. With a wide range of shock sensors developed for hard disk drives, Murata is now opening up new consumer markets. The keywords here are "vibration," "impact," and "tapping."
