Abstract
A disc drive has a head disc assembly that includes a basedeck with a threaded attachment aperture supporting a rotatable disc surface for storage of data and a rotary positionable read/write head adjacent the rotatable disc surface for writing data to and reading data from the rotating disc surface, a top cover with a mating aperture aligned to the threaded attachment aperture communicating with the basedeck to form an enclosure, a gasket constraint formed in the basedeck with an overlapping portion forming a gasket junction while supporting a tubular gasket sandwiched between the top cover and the basedeck. The tubular gasket has a first end adjacent the overlapping portion and a second end adjacent the overlapping portion; the second end communicates with a main body portion of the tubular gasket to seal the enclosure upon securing the top cover to the basedeck with a top cover fastener.
