ABSTRACT:
An apparatus for reproducing data has decoded data generated based on a reproduction signal from a recording medium in accordance with an iterative decoding process corresponding to a turbo coding method. The apparatus also has a value of a channel value constant, which is used in an iterative decoding process, controlled when the decoded data is generated in accordance with the iterative decoding process.
