The data growth speed of the big data era is continuously improved, and further, huge pressure is generated on the storage capacity and the performance.

That is, in the prior art, data cannot be evenly distributed to all optical discs, so that the memory of the optical disc recorded first is used up, and then the excessive memory of the optical disc recorded later remains, thereby causing the load imbalance of the optical disc during the recording process.
