A servowriter capable of non-invasively servowriting a magnetic recording disk drive controls the drive's on-board electro-mechanical head-position actuator system and read/write interface to self-servowrite the target drive. A head within the drive is used to write, open loop, a set of spiral tracks having embedded timing information. The spiral tracks are subsequently used to position the head so that standard embedded servo wedges can then be written. After the standard embedded servo wedges are written, the spiral tracks may be overwritten with user data.
