  1. Oct 26,  · The connection to the external environment and pressure occurs through a small hole in the enclosure (about mm in breadth), usually with a filter on the inside (the breather filter). If the air pressure is too low, then there is not enough lift for the flying head, so the head gets too close to the disk, and there is a risk of head crashes.

Its a ventilation "system" that needs flow from one end or side of the motor to the other to effectively work.

  6. WHY VENTILATION Advances in building construction techniques have led to a structure which is significantly more energy efficient and air-tight than in years past. As a result, moisture is no longer allowed to migrate freely throughout the building envelope. Trapped moisture in masonry construction, if not addressed, can lead to problems such as spalling.

  8. I think the main purpose of the "breather hole" was to releave the potentional crack problem from the end of the slit, relating to the metal technology of the era. Yes, only this is still the case. In general, for components that undergo stress loading (like a fountain pen nib), the most likely point of failure is in areas of high curvature.
