Abstract:
Embodiments of the present invention help to prevent data error occurrence in a hard disk drive by reducing the generation of dust caused by friction between a magnetic disk and a ramp. According to one embodiment, a hard disk drive comprises an enclosure, a motor for rotating a magnetic disk, an actuator for supporting a head slider for accessing the disk, and a ramp for loading/unloading the head slider disposed in the enclosure. The ramp comprises a tab slide formed of a resin material having a sliding characteristic to slide a tab at a tip end of the actuator at a specific velocity, and a slit on which a reinforcement made of a resin material with higher mechanical strength than the tab slide is formed.
