I've been trying to find a program that could let me password lock or encrypt a CD-R I burned 10 years ago. I do not remember what program I used to burn it. Would it still be possible to modify the disc's empty space to password protect it?
I thought I could try using Bitlocker to lock access to the CD but apparently it doesn't work with optical media. Is there any other method or program that could help?

There would be little point in doing this. The unencrypted information would still be accessible.
The correct solution might by to copy the disk into a veracrypt container file, then master and burn a new iso including the veracrypt file and optionally a copy of Veracrypt, and then destroy the old disk.
You talk about 10 year time frames - while in practice DVSs are often OK for that period of time, you should not rely on them for that long - if the data is valuable, burn more then 1 copy (using different brands of media) and ideally a different media as well.

"burn more then 1 copy (...) and ideally a different media as well" -- and if your data leaves any room on the media then add some redundancy with (e.g.) parchive.
1Wouldn't it be far easier to re-record the CD again (and destroy the current copy you have) and encrypt the content prior to recording it? For example, you can encrypt the content with 7-zip archiver and record such an archive. – Coder12345 – 2017-11-20T00:54:03.647
It would but I wanted to know if I could keep the CD itself as historical reference while also making the data secure. – Cesar – 2017-11-20T01:46:55.837
