THAT will give you a corrupted file!
Concatenated copy (COPY with '+') has a behavior that you need to take into
account.
PC/MS-DOS 1.00 kept track of the file size with a course granularity. (logical
sectors, not bytes) Therefore,

Ah, but most of that sort of memory has a finite number of cycles, and
Keeping the discs on the spindles will slow the rate of deterioration!
Since the discs in the middle of the stack receive less UV and less
airflow of ozone or oxygen.
Would storing in a cold dark vacuum extend the shelf-life?

Anecdotal, but I have some Fuji blanks from the 90s that still burn just fine

I can’t remember if I’ve found any Sony or TDK disks in the stuff I’ve

I find myself wondering, how well does CD-R and DVD-R media that hasn’t been
