In a coding method which does not restrict a run length of 1 while data is recordedreproduced, there are such a drawback that when an error correction is carried out, a total number of error data to be corrected is increased, and also errors of not-detectable data are increased. The hydroisomerization is carried out in the presence of a catalyst containing at least a noble metal deposited on an amorphous acid support, the metal dispersion being less than 20%. The lowest-level vending machine also imparts its unique additional data to the authentication data, received from the still-lower-level computer, to create unique authentication data and records the thus-created unique authentication data on a prepaid card to be issued thereby. The augmented instruction portion provides additional capabilities associated with the standard instruction portion. The manifold is formed of a single molded piece thereby reducing the overall tooling cost. The invention relates to both the method and compositions for such treatment.
