Abstract
The disclosure is related to systems and methods for achieving improved servo Gray code error detection and correction. A device may include a circuit configured to read servo data that is encoded using a Gray code encoding scheme to produce servo Gray code, read one or more Check bits associated with the servo Gray code, determine whether a read or write head is positioned over a target data track based on the servo Gray code and the one or more Check bits, and execute a read or write operation when the read or write head is positioned over the target data track.
