Suspensions are the mechanical support and dynamic spring that holds the magnetic recording heads over the surface of the disk. It is the suspension assembly that allows the recording head to "fly" over the disk surface at spacing of less than two millionths of an inch. The suspension also ensures the recording head does not impact the rigid disk at any time during flight. The suspension's low stiffness dynamic spring allows the magnetic heads to quickly respond to changes in the disk surface profile, while continuing to maintain the highly precise flying height required to write and read data accurately and reliably.

KR Precision has kept abreast of the latest developments in suspension manufacturing by adapting sophisticated controls to accommodate the most complex suspension design. These controls include improved gram load stability, static attitude, static roll requirements, and resonant frequency controls. The complexity of suspension designs has evolved to a point where complex rail geometries, half-etching, complex forming, and extended base plate manufacturing are now commonplace.
