Your suspicions are correct -- there is no free lunch.  Greater compression
means less redundancy, means HIGHER ERROR RATES for magnetic media (gross
generalization -- well, maybe not so gross...)

Media which use extremely high densities must use more, not less bits, to
represent the same amount of data -- and interleave it to protect against
burst errors.
