Abstract
A reproduction data recording method for an optical storage medium. The method comprises storing additional data to a first temporary region of a memory device; reading the first recorded data from the optical storage medium and storing the first recorded data to the first temporary region; reading a data segment of the second recorded data from the optical storage medium and storing the data segment to a second temporary region of the memory device; reading the first recorded data from the first temporary region and the data segment from the second temporary region, and decoding the first recorded data and the data segment to confirm accuracy of the first recorded data; reading the first recorded data and the additional data from the first temporary region, and encoding the first recorded data and the additional data to generate encoded data; and writing the encoded data to the optical storage medium.
