Apparatus and method for writing servo data to a disc of a disc drive. A disc pack comprising a disc and a spindle motor is mounted in a stationary disc servo track writing (STW) fixture, which maintains the disc in a nonrotating, stationary relation while rotating a servo write head around a circumference of the disc to write the servo data to the disc. Once the servo data are written and verified, the disc is removed from the STW fixture and installed into a disc drive. The STW fixture preferably comprises a stationary base portion, top and bottom clamp members which extend from the base portion to hold the disc in the nonrotating, fixed relation, and a rotatable enclosure, adjacent the base portion, which supports the servo write head and rotates with respect to the base portion using air bearings.
