Abstract:
In a disk drive having an inertial sensor disposed on the head thereof, a method for writing servo marks on said disk comprising the steps of:a. moving said head to a known radial position; b. writing one or more servo marks or fractional portions of one or more servo marks on said disk while holding said head at a constant radial position and applying a feedback force to said head, based on movements of said head detected by said inertial sensor, to prevent or minimize changes in said radial position; c. moving said head to a known radial position; d. determining the position of said head relative to said known position; e. applying a combination of accelerating and decelerating forces to said head, guided by said inertial sensor, to move said head radially to a radial position offset relative to said known position; f. repeating steps b through d until all of said servo marks have been written.
