Abstract
A method of writing servo information for hard disc drives, and disc drives built according to the method are disclosed. The method includes writing position reference information on a reference disc surface prior to mounting a disc assembly into a hard disc drive. Once the disc assembly is mounted in the disc drive, servo information is written onto the disc surfaces based upon the pre-written position reference information. Subsequently, the position reference information can be erased or written over by user data.
