Abstract
A hard disk drive is formed of head signal patterns, voltage patterns, a ground pattern, and a current pattern, and characterized in having a flexible printed circuit (FPC) with a hole between the head signal patterns, and the voltage patterns, the ground pattern, and the current pattern. The effect of noise on the head signal patterns is reduced in the provided hard disk drive, and vibration energy at a specific low frequency band is reduced to minimize effects on a servo control and to improve overall performance of the hard disk drive.
