System and method for tape layout optimization

A magnetic tape for use in a tape drive, the magnetic tape comprising:

• a plurality of tracks that are laid out along a length of the magnetic tape, each of the plurality of tracks being configured to receive data, the data being organized into a plurality of fixed-size subdata sets with each of the plurality of subdata sets including a plurality of codeword interleaves;
• and
• a plurality of media defect characteristics;
• wherein the data is laid out on the plurality of tracks in accordance with a tape layout allocation strategy as determined by a tape layout module, the tape layout module including:
• a tape layout optimization system including a processor that receives information on the plurality of media defect characteristics, the tape layout optimization system determining the tape layout allocation strategy based at least in part on at least one of the plurality of media defect characteristics, and the tape layout optimization system determining the tape layout allocation strategy further based on distance spectra between pairs of the plurality of codeword interleaves.
