Barracuda drives use a dedicated landing zone at the innermost radius of the
media to eliminate the possibility of destroying or degrading data by landing
in the data zone. The drive automatically goes to the landing zone when the
power is removed.
An automatic shipping lock prevents potential damage to the heads and
discs that results from movement during shipping and handling. The shipping
lock disengages when power is applied to the drive and the head load
process begins.
Barracuda drives decode track 0 location data from the dedicated servo
surface to eliminate mechanical transducer adjustments and related reliabil-
ity concerns.
A high-performance actuator assembly with a low inertia, balanced, pat-
ented, straight arm design provides excellent performance with minimal
power dissipation.
