  • Head suspension with bridge portion separating apertures near lift tab
    Patent number: 7450347
    Abstract: A magnetic disk drive is to be provided wherein a ramp and a magnetic disk do not overlap each other and both rigidity and dynamic characteristics of a suspension are maintained. In one embodiment, a ramp and an actuator lying at a retractive position are spaced away from and do not overlap an outer peripheral end of a magnetic disk. A tab is formed centrally of a front end of a load beam and is bent in U shape. Flanges are formed along both longitudinal edges of the load beam. An aperture is formed in a front portion of the load beam. The aperture permits the tab to be machined in a desired shape. An aperture is formed behind the aperture. The apertures are not formed in an integrally contiguous manner but are separated from each other by a bridge portion.
