Cheetah 10K.6 FC Product Manual, Rev. B | 5 |
3.0General description
Cheetah 10K.6 FC drives combine giant magnetoresistive (GMR) heads, partial response/maximum likelihood (PRML) read channel electronics, embedded servo technology, and a Fibre Channel interface to provide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers.
Cheetah 10K.6 FC drives are random access storage devices designed to support the Fibre Channel Arbi- trated Loop
See Figure 2 for an exploded view of the drive. Never disassemble the HDA. This exploded view is for informa- tion only. Do not attempt to service items in the sealed enclosure (heads, media, actuator, etc.) as this requires special facilities. The drive contains no parts replaceable by the user and opening the HDA for any reason voids your warranty.

Cheetah 10K.6 FC 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 heads automatically go to the land- ing zone when power is removed from the drive.
An automatic shipping lock prevents potential damage to the heads and discs that results from movement dur- ing shipping and handling. The shipping lock disengages and the head load process begins when power is applied to the drive.
Cheetah 10K.6 FC drives decode track 0 location data from the servo data embedded on each surface to elim- inate mechanical transducer adjustments and related reliability concerns.
The drives also use a
