An advanced read/write channel for magnetic disk storage

An advanced read channel for magnetic disk recording is proposed. The channel incorporates a (1,7) run-length limited code with partial response equalization and Viterbi detection. The (1,7) code reduces the severe nonlinear effects that plague thin film disk recording at high densities. It is shown...

Description
Summary:An advanced read channel for magnetic disk recording is proposed. The channel incorporates a (1,7) run-length limited code with partial response equalization and Viterbi detection. The (1,7) code reduces the severe nonlinear effects that plague thin film disk recording at high densities. It is shown through analysis and simulation that the proposed read channel is suitable for user densities of 1.5 to 2.0 and higher, for reasonable SNR and error rates.< >
