Zone based band mapping

A method comprising:

• receiving a write command to store received data to a first band of tracks of a first data storage medium, each band of tracks including multiple adjacent tracks that are at least partially overlapped;
• reading previously stored data from the first band of tracks;
• modifying the previously stored data with the received data to generate first modified data;
• determining whether to write the first modified data to the first band of tracks or a second band of tracks not including tracks from the first band of tracks based upon whether target logical block addresses (LBAs) corresponding to the received data from the write command are located within a number of last tracks of the first band of tracks;
• and
• writing the first modified data to the determined first band of tracks or second band of tracks.

A computer-readable storage device storing instructions which cause a processor to perform a method comprising:

• receiving a write command to store received data to a first band of tracks of a first data storage medium, each band of tracks including multiple adjacent tracks that are at least partially overlapped;
• reading previously stored data from the first band of tracks;
• modifying the previously stored data with the received data to generate first modified data;
• determining whether to write the first modified data to the first band of tracks or a second band of tracks not including tracks from the first band of tracks based upon upon whether target logical block addresses (LBAs) corresponding to the received data from the write command are located within a number of last tracks of the first band of tracks;
• and
• writing the first modified data to the determined first band of track or second band of tracks.
