Abstract
Provided is an optical disc recording/reproducing apparatus that performs recording and reproducing. The optical disc recording/reproducing apparatus has a recording control portion for storing, when recording data on the optical disc, an error address and an error code in a nonvolatile memory when a recording error occurs and, after recording is stopped, writing the error address and the error code read from the nonvolatile memory to a predetermined area of the optical disc, and a reproduction control portion for reading, when reproducing the data from the optical disc which is recorded according to the control of the recording control portion, the error address and the error code from the predetermined area and then storing the read error address and error code in the nonvolatile memory and, if an address of a recording error is found after reading of the data of the optical disc has started, reading the error address and the error code from the nonvolatile memory and then transferring the read error address and error code to a back-end processing portion to prevent data from being read from the address of the recording error.
