OPTICAL DISC COPY AND VERIFICATION RECORD
Purpose: document one disc and any copied or newly recorded content.
Disc ID and label:
Job: audio playback / data delivery / recovery
Disc type, drive model, software/version:
Source folder or original disc location:
Project format and intended receiving device:
Files/tracks expected:
Burn settings or read method:
Copy/burn date and error messages:
Files/tracks obtained; missing filenames:
Verification method (playback, file comparison, checksum algorithm/tool):
Verification result and exceptions:
Original-file location:
Second checked-copy location:
Review date and required software:

EXAMPLE: 120 files x 12 decimal MB = 1,440 MB; at least 3 nominal 700 MB discs before allowing for project overhead. Use the burning software to check actual capacity.
A successful file hash comparison checks file bytes, not disc lifetime. Record missing files explicitly. Keep original media until recovery and retention decisions are settled.
