Patent abstract
In accordance with various embodiments, a radial separation distance between first and second servo seams on a storage medium is determined, and a scaled position signal is generated in relation to the determined radial separation distance and a measured position signal. An error runout correction (ERC) value is obtained from the scaled position signal, and the ERC value is thereafter used to compensate for repeated runout (RRO) error.
