| Abstract: | In this paper,the application of cross interleaved reed solomon code (CIRC) in rotary head digiatl magnetic recorder is discussed.The elemental method on coding and decoding of RS code in time domain is presented,and the hardwave implementation of CIRC encoder/decoder with FPGA and L6471X Sery VLSI is given.Experiment shows that by adding CIRC ECC (error correcting circuit),the BER (bit error rate) can be decreased from 10 -3 to less that 10 -8 .Finally,the reason for error is analysed. |
