Abstract:
1. A encoding method of record medium, for modulating a sequence of original data of m digits as a sequence of digital data of n digits, the encoding procedures of the method involving accessing the original data of the m digits after setting an initial type, obtaining a corresponding set value (i) after the original data of the m digits is transformed, and searching a corresponding digital set (Si) in a digital table, then obtaining a unique digital vector (Vj) in the digital set via a sieve procedure, picking the digital data of the n digits of the digital vector, finally outputting the encoding results, the digital data of the n digits be output to the record medium to store after repeating the encoding procedures, said method comprising the steps of: accessing the original data of the m digits; transforming the original data of the m digits into the set value, and searching the corresponding digital set in the digital table; processing the sieve of the digital vector; outputting the digital data of the n digits; and generating a write-in signal; wherein when satisfying the conditions of the step of accessing the original data of the m digits, the method continuing the encoding procedures; when unsatisfying the conditions of the step of accessing the original data of the m digits, the method terminating the encoding procedures.
