A suspension assembly and an actuator having the same, which are of a hard disk drive (HDD). The suspension assembly includes a load beam coupled to an end of a swing arm of an actuator; a flexure attached to the load beam to support the slider; and a tip-tab which extends from a front end of the load beam to contact a ramp when the read/write head is parked, wherein a width of a contact part of the tip-tab that contacts the ramp is wider than other parts of the tip-tab. A width of a part of the tip-tab engaged with the load beam and a width of a front part of the tip-tab are smaller than the width of the contact part. The width of the tip-tab increases gradually from the front end of the load beam up to the contact part, and decreases gradually after the contact part.

Suspension assembly and actuator having the same in hard disk drive

A ramp to park a read/write head includes a fixed portion fixed to a base member of the hard disk drive, and a supporting portion to contact and support the tip-tab of the suspension assembly and includes an inclined rail surface and a horizontal rail surface which extend in a moving direction of the tip-tab, wherein a rail boundary between the inclined rail surface and the horizontal rail surface is inclined with respect to a lengthwise axis of the tip-tab. The rail boundary can be a straight line inclined at an angle with respect to the lengthwise axis of the tip-tab, or can be curved toward the horizontal rail surface or the inclined rail surface.
