FILTERING DEVICE OF HARD DISK DRIVE

摘要

PURPOSE: A filtering device of a hard disk drive is provided to effectively prevent damage on a hard disk and a magnetic head by filtering fine particles easily separated from a hard disk surface. CONSTITUTION: A filter(70) filters fine particles from flowing air in a housing(10) generated by rotation of a hard disk(40) installed in the housing including a cover(20) and a base(30). A plurality of turbulent flow inducing members(91a,92a,93a,94a) are formed on a bottom surface(20a) of the cover and a top surface(30a) of the base to make flowing air turbulent flow by changing the flow of flowing air. An air guide(90) guides flowing air including the fine particles separated from a hard disk surface(40a) toward the filter.
