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.
