Isolation of an HDD production device such as a servo track writer from external vibration is provided. The isolated device and its nest or support are suspended in a fashion to allow one, two or three degrees of angular or rotational freedom of movement. The points of suspension are above the center of mass of the isolated device, alone or combined with its nest, and gravity will self-align the isolated device in the manner of an unforced pendulum. A relatively large moment of inertia for at least one direction of angular movement is provided, e.g., by positioning at least one suspension point spaced a relatively large distance from the center of mass to provide a large moment arm for such movement.
