8 Cheetah 10K.7 SCSI Product Manual, Rev. D
Cheetah 10K.7 SCSI 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 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.
A high-performance actuator assembly with a low-inertia, balanced, patented, straight-arm design provides
excellent performance with minimal power dissipation.

3.2 Media characteristics
The media used on the drive has an aluminum substrate coated with a thin film magnetic material, overcoated
with a proprietary protective layer for improved durability and environmental protection.
