Abstract

This paper proposed a method of reducing a noise in hard disk drive. This method is performed through three parts of procedures. First procedure is sound-oriented experiment, which contains sound intensity techniques and measurements of sound pressure level and sound power. Second is vibration-oriented experiment, which contains FRF(Frequency Response Function) analysis and disk vibration reduction techniques. And the third is computer-oriented simulation, which contains modal analysis and force vibration analysis using ANSYS and sound radiation prediction using SYSNOISE. As these three parts can affect with each other, they should be considered and conducted simultaneously. Through this procedure sound power is measured 2.7 Bels in idle-spinning mode, which is the lowest noise level in the HDD industries.
