More than 70 percent of the world's information is stored in Hard Disk Drives (HDDs) and this is expected to continue to be true over the next decade despite competition from NAND flash memory. HDDs have the attributes of extremely high capacity at low cost (10x lower than NAND), high ...
Optimization of a magnetic disk drive actuator with small skew actuation Currently the utilization of the voice-coil motor for actuating read/write head elements in magnetic hard disk drives results in a skewed actuation, which ... Z He,EH Ong,G Guo - 《Journal of Applied Physics》 被引量:...
A decoupled controller architecture and discrete time pole placement design methodology is proposed for dual-stage servo controller design of magnetic hard disk drives. The methodology was applied to the controller design of a dual-stage servo with a MEMS microactuator (MA) which rotates the slider...
