Vibration Protection
Enhanced RAFF™ technology includes
sophisticated electronics to monitor the
drive and correct both linear and
rotational vibration in real time. The result
is a significant performance improvement
in high vibration environments over the
previous generation of drives.

Dual actuator technology
A head positioning system with two
actuators that improves positional
accuracy over the data track(s). The
primary actuator provides coarse
displacement using conventional
electromagnetic actuator principles. The
secondary actuator uses piezoelectric
motion to fine tune the head positioning
to a higher degree of accuracy.

StableTrac™
The motor shaft is secured at both ends
to reduce system-induced vibration and
stabilize platters for accurate tracking
during read and write operations.
