I tried to write an .iso file on a CD-R, but I got an error in process.

BraseroLibburn called brasero_job_set_current_action
BraseroLibburn called brasero_job_get_session_output_size
BraseroLibburn called brasero_job_set_current_action
BraseroLibburn called brasero_job_get_session_output_size

    error       = 1
    message = "SCSI error on write(1136,16): [5 64 00] Illegal mode for this track"
BraseroLibburn stopping
Session error : SCSI error on write(1136,16): [5 64 00] Illegal mode for this track (brasero_burn_record brasero-burn.c:2856)

When I opened the resulted disk, most files are ended up written there, but I'm not sure if that's all of them. When I tried to boot from this disk, nothing happened. How to check if this .iso was burned correctly?

I couldn't find a duplicate, so I'll readapt an old answer of mine.

You can check the integrity of the image written to the CD by checking its MD5 sum against the original ISO's MD5 sum:

  1. Check the original ISO's size:

    % ls -l archlinux-2015.10.01-dual.iso 
-rwxrwxr-x 1 user user 689963008 nov 22 21:35 archlinux-2015.10.01-dual.iso

  2. Run this command (change 689963008 according to the original ISO's size):

    sudo dd if=/dev/cdrom iflag=fullblock count=$((689963008/512)) 2>/dev/null | md5sum -

  3. Check the output against the original ISO's MD5 sum:

    % md5sum archlinux-2015.10.01-dual.iso
b6781474851992cd9deb03b93a3f9503  archlinux-2015.10.01-dual.iso

If you want to get fancy:

  1. Enable the Universe repository (you can do that in Software & Updates);

  2. Install pv: sudo apt-get install pv;

  3. Check the original ISO's size:

    % ls -l archlinux-2015.10.01-dual.iso 
-rwxrwxr-x 1 user user 689963008 nov 22 21:35 archlinux-2015.10.01-dual.iso

  4. Run this command (change 689963008 according to the original ISO's size):

    sudo dd if=/dev/cdrom iflag=fullblock count=$((689963008/512)) 2>/dev/null | pv -s 689963008 | md5sum -

  5. Check the output against the original ISO's MD5 sum:

    % md5sum archlinux-2015.10.01-dual.iso
b6781474851992cd9deb03b93a3f9503  archlinux-2015.10.01-dual.iso

I suppose you're using an empty CD-R. This can only be written once, and after that it's only readable...

Which means; since the .iso hasn't burnt onto the CD-R correctly, you can't do anything about it.

Throw it away, and maybe try using a CD-RW?

i am the developer of libburn.

The burn run was a clear failure. Possibly because the CD was already written and closed. There were at most 1136 * 2048 bytes written (~ 2 MB). So everything else which you can read from the CD must stem from a previous burn run.

Have a nice day :)
