A system, method, and apparatus for solving flow-induced track
misregistration (TMR) problems in hard disk drives (HDD). Boundary layer
manipulation techniques are applied to the airflow in the HDD, such as
boundary layer suction with slots or holes, and wall damping techniques,
such as an open honeycomb seal and Helmholtz resonators. These
flow-conditioning solutions reduce the turbulence intensity throughout
the HDD to reduce TMR. These solutions achieve these goals while
minimizing increases in the running torque needed to overcome their
inherent rotational drag.
