Abstract
A method for detecting errors in a servo system of a magnetic storage drive includes writing a plurality of data tracks at a pitch, detecting a position of an edge of at least two of the data tracks under control of a servo system (e.g., an optical or magnetic servo system), and determining an error in the servo system based on the detected positions and known pitch of the data tracks. Differences in the track edge positions of the tracks from the positions at which they were written may indicate errors in the optical servo system (e.g., non-linearity errors, as well as other errors such as electrical, temperature, or the like). Determined errors may be stored with a look-up table of positional errors or used to normalize a position algorithm associated with the servo system.
