摘要： The present invention relates to data processing apparatus and method, and a program which make it possible to scatter burst errors with respect to both codes of a product code.A block-wise interleaver performs interleaving A, which is a process of inputting data in the order of the column direction as one direction, and reading the data in the order of the direction diagonally downward to the right, NB bits by NB bits (=block by block) with respect to ND×NB×NA bits of a product code. Next, the block-wise interleaver performs interleaving B, which is a process of inputting data in the order of the column direction as one direction, and reading the data in the order of the row direction as the other direction, NB bits by NB bits with respect to (NC−ND)×NB×NA bits representing the parity portion of an inner code indicated by P, of the product code. The present invention can be applied to, for example, a recording/reproducing apparatus.
