Abstract
A device for detecting and correcting errors in a data stream. For example, a device for detecting and correcting errors in a data stream including identifiers for a track address or identifiers for encoded words in a wireless transmission. The devices employ a class of error correction codes to, for instance, encode track addresses on a surface of a data storage medium. The encoding modifies natural track addresses so that the difference between bit sequences in adjacent track addresses is constant while simultaneously enabling both error detection and error correction, thereby enabling more accurate head positioning in a data storage device, in one embodiment.
