step S101: and judging whether the target file capacity of the target file to be recorded is larger than the target optical disc capacity corresponding to each target optical disc to be recorded. In this step, if the capacity of the target file to be recorded is too large, a target disc cannot accommodate the target file, the content of the target file must be divided, and then the divided target file is recorded into the target disc.
Step S102: if the target file capacity of the target file to be recorded is larger than the target optical disc capacity corresponding to each target optical disc to be recorded, whether the target file is suitable for being recorded on the target optical disc on average is further judged according to the target file capacity, the target optical disc capacity and the number of target optical discs corresponding to all the target optical discs. In this step, the target file can be recorded on the target disc on average, or the target file can be recorded on the target disc randomly or in a planned manner, with the maximum recording capacity of the target disc.

In this embodiment, optionally, the cutting the target file into a plurality of target subfiles, and a file capacity corresponding to at most one of the target subfiles is different from the target disc capacity in all of the target subfiles, then includes:
and encrypting each target subfile, wherein each target subfile corresponding to the same target file has the same encryption password. Because the security and stability of the file recorded on the optical disc can be interfered and damaged by various factors, great file loss is caused, and the security and stability of the file recorded on the optical disc can be ensured by encrypting the target subfile.
In this embodiment, optionally, the averagely cutting the target file into a plurality of target subfiles and performing preset processing includes:
and averagely cutting the target file into a plurality of target subfiles, and encrypting each target subfile to ensure that the encryption passwords of each target subfile corresponding to each target file are the same, so that the content of the file is not confused.
In this embodiment, optionally, after the target file is averagely divided into a plurality of target subfiles and preset, the target subfiles are respectively recorded to corresponding target optical discs, and then the method includes:
and generating a target capacity identifier on each target optical disc, wherein the target capacity identifier is used for indicating the file capacity corresponding to the target file recorded on the target optical disc.
The embodiment of the invention judges whether the target file capacity of the target file to be recorded is larger than the target optical disc capacity corresponding to each target optical disc to be recorded, if so, further judges whether the target file is suitable for being recorded on the target optical disc on average according to the target file capacity, the target optical disc capacity and the number of the target optical discs corresponding to all the target optical discs, and if so, the target file is cut into a plurality of target subfiles on average and is recorded on each corresponding target optical disc respectively after preset processing. In addition, the invention carries out encryption processing on the target (sub) file, and can ensure the safety and stability of the file recorded on the optical disk.
