Recent hard disk drives with higher track density need countermeasures for flow-induced vibration (FIV) such as disk and arm vibrations without increasing the power consumption. The authors propose a new spoiler, "window spoiler", the wings of which each has a large hole and the same outer size as the original spoiler. This paper describes how a window spoiler can reduce FIV, better than the spoiler without a hole. The reduction mechanism was clarified by using particle image velocimetry.
