ABSTRACT:
An encoding device includes a buffer for performing EDC generation, scrambling and ECC generation on user data arranged along user data direction Q that is read out from a data buffer of SDRAM and storing the operation results, a substitution buffer for repeatedly reading out the user data by burst transfer from the data buffer and outputting the data in recording frame direction P, and a scrambler for scrambling the data output from the substitution buffer along the direction P according to the operation results and outputting scrambled data. The substitution buffer is configured by SRAM and has a memory capacity of equal to or larger than a minimum capacity to output user data in the direction P and smaller than a memory capacity of the data buffer.
