Abstract
A head and gimbal assembly (“HGA”) for supporting a pair of read/write heads at a desired fly height above a pair of adjacent discs. The HGA includes a rigid support arm, and a pair of thin, sheet metal suspensions mounted on opposed surfaces of the support arm. An end of each of the suspensions extends beyond an end of the support arm. These overhanging end portions include cutout sections defining a pair of back-to-back gimbals on which the read/write heads may be mounted. The suspensions may additionally include electrical connectors etched into the surface for transferring electrical signals between the read/write heads and the control electronics of the disc drive. In operation, a single HGA may be located between two adjacent discs, so that one of the heads on the HGA performs read/write operations on one of the two adjacent discs, and the other of the heads performs read/write operations on the other of the two adjacent discs. The HGA preferably supports the heads so that they exert little or no force against the discs.
