Abstract
A recording apparatus has a check-after-write function for reproducing and checking the recorded state of a recorded track. When overwriting of data is started, an identification number to be stored in a track is set at a fixed value, and check-after-reproduction is performed by the fixed value during reproduction in which a check is made. Also, a reproducing apparatus includes a system for detecting that a very small error segment has occurred on the data and for making the data of the error segment invalid or not outputting the data when it is determined that the error segment has occurred.
