METHOD AND APPARATUS FOR MULTIPLICATIVE NOISE PRECOMPENSATION FOR MAGNETIC RECORDINGS |
| 摘要 |
Electronics (40) implements the multiplicative noise model of the present invention. The diagnostic signal generator (50) processes the data signal s(t) to produce a diagnostic signal. The medium noise estimator (60) predicts repeatable noise components based on analysis of the diagnostic signal. Using the estimate of the medium noise, the precompensated signal generator (70) produces a corrected write signal.
