The behavior of the air flow inside a hard disk drive is evaluated by a three-dimensional unsteady-flow analysis technique called large eddy simulation (LES). The simulation shows that the fluctuation of the aerodynam...

This paper presents a method for simultaneously detecting the position and timing error in bit patterned media (BPM). Conventionally the position error is determined only in the servo area while the timing error is de...
