6 Barracuda 9LP Product Manual, Rev. C
Barracuda 9LP drives use a dedicated landing zone at the innermost radius of the media to eliminate the pos-
sibility of destroying or degrading data by landing in the data zone. The drive automatically goes to the landing
zone when power is removed.
An automatic shipping lock prevents potential damage to the heads and discs that results from movement dur-
ing shipping and handling. The shipping lock automatically disengages when power is applied to the drive and
the head load process begins.
Barracuda 9LP drives decode track 0 location data from the servo data embedded on each surface to eliminate
mechanical transducer adjustments and related reliability concerns.
A high-performance actuator assembly with a low-inertia, balanced, patented, straight-arm design provides
excellent performance with minimal power dissipation.
