Abstract
A disk drive includes a storage disk, a suspension and a slider assembly. The slider assembly includes a trailing half having a surface area, and a leading half having a substantially similar surface area to that of the trailing half. The percentage of the surface area of the trailing half that is directly secured to the suspension is greater than the percentage of the surface area of the leading half that is directly secured to the suspension. In another embodiment, the slider assembly includes a top surface that is secured to the suspension so that during an increase in temperature of the suspension only a portion of the top surface is subjected to a force that causes concavity of the slider assembly along a crown and/or a cross-crown direction. In yet another embodiment, the slider assembly is secured to the suspension so that a portion of the slider assembly cantilevers away from the suspension. In a further embodiment, the slider assembly has a leading edge and an opposing trailing edge. In this embodiment, the slider assembly is secured to the suspension so that an increase in temperature of the suspension causes more cross-crown concavity relative to the storage disk at the …
