Abstract :
Summary form only given. The design of a Viterbi detector for high speed disk drive channels is presented. The detector is a soft decision detector that operates on a time varying trellis based on a matched spectral null code. The design was developed by creating a high-level model of the system to resolve high-level design issues. Standard design tools were used for logic simulation and layout generation. The design has been fabricated and verified to be fully functional
