摘要： An error correction coding device includes a time divider for dividing field data of L packets into N data packets and (L-N) parity packets, a first RS (Reed-Solomon) encoder adding parities of a predetermined number of bytes to the data packets, respectively, a storage unit for storing the data packets, and a second RS encoder generating parity packets corresponding to the stored data packets. An error correction decoding device includes a first RS decoder correcting errors in a horizontal direction of the field data using parities of the predetermined number of bytes included in the L packets, a storage unit storing the error-corrected data packets, and a second RS decoder correcting errors in a vertical direction of the field data using the parity packets. Thus, the error correction can be strongly performed using parities existing in the horizontal and vertical directions with respect to the field data.

摘要： A digital signal detector for a digital magnetic recording/reproducing device detects corrected signals using a differentiation feature of a recording/reproducing segment of the device, to reduce performance degradation due to signal distortion. The detector includes a precoder for converting an input digital signal into a non-return-to-zero-inverter (NRZI) waveform signal; a recording/reproducing portion for recording the signal output from the predecoder and reproducing the recorded signal; a linear equalizer for compensating the distorted amplitude of the signal reproduced by the recording/reproducing portion; a signal corrector for correcting a signal output from the linear equalizer using a signal correlation process; an integration detector for integrating the signal corrected by the signal corrector; and a predecoder for decoding the signal integrated by the integration detector into its original signal. The digital signal detector corrects reproduced signals, integrates the corrected reproduction signals having differentiated components of the recording/reproducing portion and then limits the integrated signals to a certain value, thereby reducing errors due to the accumulation of integration error values and reducing hardware volume.
