System and method for tape layout optimization

A method for determining a tape layout allocation strategy for laying out data on tape, 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, the tape including a plurality of media defect characteristics, the method comprising the steps of:

• receiving information on the plurality of media defect characteristics with a tape layout optimization system including a processor;
• and
• determining the tape layout allocation strategy with the tape layout optimization system based at least in part on at least one of the plurality of media defect characteristics, and further based on distance spectra between pairs of the plurality of codeword interleaves.

A tape layout module for determining a tape layout allocation strategy for laying out data on a magnetic tape, 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, the tape including a plurality of media defect characteristics, the tape layout module comprising:

• 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 wherein the tape layout optimization system generates a plurality of coefficients, αi(bi), that are the result of a modeling of the plurality of media defect characteristics.
