There is provided a method of processing data for generating an error correction product code block devised so as to maintain the current level of redundancy after the error correcting ability is modified as a result of advancement of simiconductor and data, recording/transmission technologies. Unlike any known technique of configuring a Reed-Solomon error correcting product code block of (M+PO)x(N+PI) bytes for an information data of (MxN) bytes, an error correcting product code block data structure is obtained by configuring a (Kx(M+1)x(N+P))-byte Reed-Solomon error correcting product code block for (KxMxN)-byte data making K variable to consequently make the entire size of the …

Why it's free to use
- Filed April 8, 1996 and granted November 28, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 8, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 8, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
