In all seriousness, I’ve always thought the platters were extremely thin inside a HDD, but never actually had one open. That looks quite thick actually.
This is maybe 10 years old and a single platter drive. It’s possible multi-platter drives would have much thinner ones.
Too big, use this:
What you have there is a hard disk drive. In order to fit it into the CD drive (or Compact Disk drive) you need to first compact it! A hydraulic press is the preferred method.

It’s a common misconception to try this in the cd drive. You actually have to insert it in floppy drive slot (nowadays only really old computers have them). You might have to push it in with a bit of force though, because they tend to lock up if you haven’t used them for a while…
Have you tried pushing it really hard?
maybe op didn’t realize it’s a HD, thus it needs to be driven hard into position
