An information recording and reproducing apparatus includes an encoding circuit for encoding information codes and for adding redundant codes to the information codes to form error detection and/or correction codes, a recording and reproducing head for recording and reproducing the information codes and the redundant codes on and from the recording medium and a decoding circuit for detecting and/or correcting errors in reproduced information codes by using the redundant codes. The apparatus has an output terminal for externally outputting the information codes partially processed through the decoding circuit and only a part of the redundant codes.
