  • Patent number: 11430474
    Abstract: A hard disk drive suspension includes a suspension tail configured to electrically connect to a read-write transducer at a distal end and extending in a proximal direction toward a tapered tip at a proximal end, where the tapered tip comprises a decreasing taper that narrows in the proximal direction. Hence, structural overlap among adjacent suspension tails in misalignment scenarios and consequent marginalized electrical connections between the suspension tail and a corresponding flexible printed circuit are inhibited. The most proximal electrical pads of the suspension tail may be configured with a different aspect ratio, or in a fewer number of lines, from other adjacent electrical pads, thereby fitting within the narrowest portion of the tapered tip.
