Abstract
An objective of the present invention is to provide a decoder, a perpendicular magnetic recording and reproducing device, a receiving device, and a decoding method that are used for performing decoding resistant to burst errors such as a pole-erase phenomenon, where the burst errors do not have amplitude fluctuation, without the addition of a special code (redundant code) for detecting burst errors. The present invention is a decoder, a perpendicular magnetic recording and reproducing device, a receiving device, and a decoding method that perform a decoding process on an encoded data signal, wherein a parity check is performed on the encoded data signal that is encoded with a low density parity check code to output burst information.
