FDB (Fluid Dynamic Bearing Motors)
Fluid dynamic bearing motor is accelerating as hard disk drive industry standard design, for two reasons: In order to achieve higher areal density and data transfer rate (to increase hard drive performance and maintain a high reliability) and to reduce the noise (in line with consumer by the electronic equipment market requirements).
Fluid power motors can not be restored at a lower deflection (nonrepeatable runout; NRRO) and position error signal (position error signal; PES) subject to a higher speed, to ensure that the next generation of hard disk drives to reliably track from a very narrow magnetic deposit obtain information.
New fluid power motor is compatible with next-generation performance requirements, but they still have to face some major challenges, including lower manufacturing costs (the cost of the motor falls below the equivalent level of ball bearings), ensure that no oil leakage, and improving hard disk drive lifetime.
FDDI (Fiber Distributed Data Interface)
Fiber distributed data interface design is mainly used as a campus backbone network or high-performance local area network, the rate of up to 100-Mbps. Shared domain of FDDI-based network of the city (Metropolitan Area Network; MAN) can be connected via OC-3 Synchronous Optical Network (SONET) to form a wide-area network.
Fiber distributed data interface standard copper cabling if they were called Copper Distributed Data Interface (Copper Distributed Data Interface; CDDI). Fiber distributed data interface drawback is that transmission distance is limited. FDDI-II is to improve the shortcomings of FDDI and ATM with a longer short.
FDISK Software
Used to plan on a DOS partition (PARTITION) software tool (UTILITY).
