Page 27: Rotary Acceleration Feed Forward (Raff)
EX800M Product Features Rotary Acceleration Feed Forward (RAFF)™ Rotary Acceleration Feed Forward (RAFF) helps to overcome the effects of rotational vibration (RV) on a hard drive by generating an additional control effort to counter the RV disturbances, thereby keeping the drive head(s) within the safe operating region during reading and writing operations. Figure 3-1. -
Page 28: Intelliseek
Product Features EX800M bits, the PMR recording layer tends to be thicker than that used for longitudinal recording, providing increased signal for the read heads. All of these benefits enable WD engineers to reliably pack more data on a given disk than is possible with conventional longitudinal recording. IntelliSeek WD’s unique IntelliSeek technology proactively calculates an optimum seek speed to eliminate hasty movement of the actuator that produces noise and requires power, which is common in other drives. -
