Abstract: A system (110) and method for performing a combined media certification and servo data writing function is disclosed. The system and method include mounting a plurality of media, such as hard disks (121), to a spindle (120) and using at least one positioner (117) to move multiple read write heads (113) over disk surfaces according to multiple specific aspects of the invention. One aspect of the invention comprises performing certification on a first pass, writing servo pattern data on a second pass, and verifying servo data on a third pass over the media. The system may require high performance read/write heads, writing of coherent patterns in addition to servo patterns, use of multiple positioners, and additional hardware to perform the joint certification and servowriting function.
