Abstract
Systems and methods provide for one or more server computers communicatively coupled to a network and configured to: generate a code construction for a file, including layers, each at a different code rate; calculate optimized code parameters, including storage efficiency, error-correction capability parameters, and constraints on error patterns; use the plurality of layers and optimized parameters to encode the file on a physical storage media; detect an error on the physical storage media; identify an error location within a first layer encoded at a first code rate; mark the error location as an erasure; and identify the erasure and a second error location for a second error location within a second layer, higher than the first layer, encoded at a second code rate.
