ABSTRACT:
A reproduction method includes a step of performing error correction of the first coded data piece and generating error location information which represents an error location of the first coded data; a step of generating erasure locator information which represents an erasure position of the second coded data piece, based on the error location information; and an erasure error correction step of performing erasure error correction of the second coded data piece based on the erasure locator information. The erasure locator information generation step includes the step of, when the error location information indicates that no error is detected in the Nth first symbol and the (N+2)th first symbol and that an error is detected in the (N+1)th first symbol, determining at least one of the plurality of second symbols provided adjacent to the (N+1)th first symbol as representing erasure.
