Patent ID: 8266502

Claim:
A recording/reproducing apparatus, comprising: an encoding section configured to encode data that is to be recorded onto a recording medium into an LDPC (Low Density Parity Check) code; a decoding section configured to decode the LDPC code read out from the recording medium; a first judging section configured to judge a block with a recording error based on one of a block error flag and an iterative decoding count output from the decoding section; a memory section configured to store data of a block reproduced from the recording medium; and a second judging section configured to judge, based on one of a block error flag and an iterative decoding count obtained at a time of decoding a rewritten block and one of a block error flag and an iterative decoding count obtained at a time of decoding the same block before being rewritten, whether to overwrite reproduction data of the block before being rewritten that is stored in the memory section with reproduction data of the rewritten block.
