Abstract: A method includes moving data in a defect range from a defective area of a data storage medium to a reserve area of the data storage medium, and identifying the defect range by an address of a start of the defect range and a defect length. A logical address table is updated with the address of the start of the defect range, the defect length and an offset to the reserve area.

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.
