Abstract: Systems and methods for zone-based band mapping in a data storage device are disclosed. In one embodiment, a device may comprise a first data storage medium including a first band of tracks and a second band of tracks, each band of tracks including multiple adjacent tracks that are at least partially overlapped. The device may further comprise a processor configured to receive a write command to store received data to the first band of tracks, read previously stored data from the first band of tracks, modify the previously stored data with the received data to generate first modified data, write the first modified data to the second band of tracks, and assign a first data storage location indicator previously associated with the first band of tracks to the second band of tracks.
