Abstract
A reproduction apparatus which can perform error correction decoding processing which allows data at a linking portion of linking recording to be regenerated as much as possible to restrict the invalid data area at the linking portion to a necessary minimum magnitude is disclosed. The production apparatus reproduces a recording medium on which data coded in two or more different series by error correction coding are linking-recorded such that they are recorded at continuous positions at discontinuous points of time and comprises linking position detection means for detecting a linking portion of linking-recording, wrong correction detection means for detecting wrong correction based on the error correction code, and means for rendering the wrong correction detection means inoperative at the linking portion detected by the linking position detection means.
