, to ByER at the constrained decoder output, and to EFR at the ECC decoder output, to provide various assessments of the PCcode-based systems.  ...  The constrained decoder and ECC decoder operate on the output of the detector to provide an estimate of the original user data that was input to the recording system.  ...  The effect of interleaving is to spread an uncorrectable error burst into multiple ECC codewords, so that they appear to the decoder as single symbol errors or shorter correctable burst errors.  ...
