Abstract: A method includes monitoring operations performed on tracks in a main storage area of a disc, and identifying a track of the tracks in the main storage area susceptible to adjacent track interference (ATI). When a track is identified, the identified track or an adjacent track which contributes to ATI of the identified track is remapped to an ATI safe zone of the disc having a tracks per inch (TPI) density lower than a TPI density of the main storage area.
