    摘要： System and method for generating a Position Error Signal (PES) reference curve in data storage devices are provided. The method includes scanning a distance of at least one Track Pitch (TP) in a cross-track direction in each servo-burst along a predefined path. One or more TPs in each servo-burst are scanned with a read head. The method further includes, calculating a plurality of samples of each differential signal. A differential signal corresponds to a first read-back signal and a second read-back signal. Thereafter, a plurality of normalized signals are determined. A normalized signal is determined by dividing each sample of the differential signal with a normalization constant. The plurality of normalized signals are combined to generate the PES reference curve.

    摘要： A storage device including a storage medium for storing data in the form of marks in multiple tracks aligned along track center lines, at least one read transducer for writing and reading said data stored in said storage medium, and an actuator for moving said storage medium relative to said at least one read transducer. The storage device further includes stored servo sequences, which are replicated by use of at least two different types of servo marks displaced by a given unique distance in a cross track direction relative to a respective track centerline, wherein the storage device is operable to retrieve servo sequences using read-back signals obtained from at least two different types of servo marks.
