I’ve got Optiarc DVD RW AD-7580S FX20 drive from old laptop that I converted to external drive by using a caddy made for that purpose.
It works fine, except 4x speed when writing DVD+RW discs. I’ve noticed the burns are mostly unreadable and way darker. Probably bad laser power level.
So, I got the idea to make stripes on the disc.
At first I tried it with multi-session, but after a few stripes it would always die after some 4x burn. Occasionally it could load and append it after many long re-tries, but it eventually failed way too early.
Since I couldn’t think of a better way with my tiny brain/braincell clump, I decided to do it from outside in. Burning large image decreased by 200MiB each time I alternated the speed between 4x (dark) and 2.4x (bright).
4,200MiB 4x
4,000MiB 2.4x
3,800MiB 4x
3,600MiB 2.4x
3,400MiB 4x
3,200MiB 2.4x
3,000MiB 4x
2,800MiB 2.4x
2,600MiB 4x
2,400MiB 2.4x
2,200MiB 4x
2,000MiB 2.4x
1,800MiB 4x

1,400MiB 4x
1,200MiB 2.4x
1,000MiB 4x
800MiB 2.4x
600MiB 4x
(inner 417MiB is 2.4x only)

I wasn’t sure if zeroes would change the appearance so I used random data.

If only I still had any optical drive and blank optical media
Yamaha did it natively and called it Yamaha Disc T@2, it was pretty cool. Needed their CRW-F1 drive and a CR-R disc with a dark color bottom (the blue azo discs worked best). I still have a stack of those discs somewhere.
For anyone curious, LGR did a video on these! Might give a bit of an extra visual to the end product.
I still have an optical drive in one of my desktops and a ton of blank CDs/DVDs collecting dust on my shelf. Maybe I should do this. But then I’m not sure what I would do with the final product. It would just continue to collect dust on my shelf. :(
