Summary:Approaches to improving head positioning accuracy in a hard disk drive, by suppressing airflow disturbances that would otherwise cause unwanted component vibration, include a voice coil motor having a sidewall spanning a gap between the VCM upper yoke and lower yoke. This VCM sidewall also serves as the inner wall of a bypass channel, for diverting airflow away from the actuator arm and associated components.
