Whoops. I think it is better to use Session-At-Once here. This is
because all computer data files are written into just one track per
A disk can contain many sessions, which in turn can contain the required
number of tracks. Normally CD-ROMs and Audio CDs only have one session

I assume the multiple ballots here are duplicate ballots, which act as
backups just in case of data corruption. Even with the start program and
duplicate ballots, you should be able to put in about 1/4 million ballots
on the disc. However, this does very heavily depend on the computer file
system used on the disc.

Using the Domesday Project as an example, all I was trying to say was that
it is possible to get an 8 bit CPU to run an optical disk. The Z80 is an
8 bit CPU. However, I doubt anybody has written CD burner code in Z80.
Anyway, the Z80 would be virtually dependent on how the CD burner was
wired to it. This would depend on how the "wiring up" has been designed.
Only after knowing this would you be able to program the Z80
