Abstract
In a digital data recording and reproducing device, an operation of error detection is perlormed by circuits (51, 52) with respect to data with weighting provided with a code word dissolution of M bits in upper m1 bits of the most significant bit side of great weighting and lower m2 bits of the least significant side of small weighting. Error concealment (53) is carried out for each of these error detections. When reproducing data at a different tape speed from that at the time of recording, the operation of the circuit (52) for detecting an error in lower m2 bits is inhibited, and the reference of judgement of an error in the data is altered.
