Hard disk drive frame
A hard disk drive frame is provided. The distances from its hard disk drive fixing parts to the substrate center are not the same. During the process of vibrational energy transfer, three-dimensional reactions are induced correspondingly to cancel the kinetic energy transfer. The reactions generated at the static balance point in the three dimensions interfere one another to destroy vibrational frequencies in specific directions. Therefore, the disclosed hard disk drive is resistant to vibrations and suffers less from the resonance effect.
