what determines overburn capability of CD-R?

I had a 733MiB ISO image which I tried to write to a CD-R. I had two CD-R disks from different manufacturers. With first CD-R disk(TDK) the burning process failed, but using the second CD-R(EMTEC), it succeeded. Command used for burning was wodim -v speed=1 dev='/dev/scd0' -sao -overburn /home/martin/Downloads/linux.iso *Unsuccessful attempt:* root@T42:~# ls -lh /home/martin/Downloads/linux.iso -rw-r--r-- 1 martin martin 733M Feb 7 19:30 /home/martin/Downloads/linux.iso root@T42:~# wodim -v speed=1 dev='/dev/scd0' -sao -overburn /home/martin/Downloads/linux.iso TOC Type: 1 = CD-ROM scsidev: '/dev/scd0' devname: '/dev/scd0' scsibus: -2 target: -2 lun: -2 Linux sg driver version: 3.5.27 Wodim version: 1.1.11 SCSI buffer size: 64512 Device type : Removable CD-ROM Version : 5 Response Format: 2 Capabilities : Vendor_info : 'HL-DT-ST' Identification : 'DVDRAM GSA-4083N' Revision : '1.00' Device seems to be: Generic mmc2 DVD-R/DVD-RW.

In addition, any ideas what the *"low Beta category (B-) (4)"* and *"high Beta category (A+) (3)"* mean in CD-R ATIP info section?
