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.isoUnsuccessful 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.isoroot@T42:~# wodim -v speed=1 dev='/dev/scd0' -sao -overburn /home/martin/Downloads/linux.isoTOC Type: 1 = CD-ROMscsidev: '/dev/scd0'devname: '/dev/scd0'scsibus: -2 target: -2 lun: -2Linux sg driver version: 3.5.27Wodim version: 1.1.11SCSI buffer size: 64512Device type    : Removable CD-ROMVersion        : 5Response Format: 2Capabilities   : Vendor_info    : 'HL-DT-ST'Identification : 'DVDRAM GSA-4083N'Revision       : '1.00'Device seems to be: Generic mmc2 DVD-R/DVD-RW.Current: 0x0009 (CD-R)Profile: 0x0012 (DVD-RAM) Profile: 0x0011 (DVD-R sequential recording) Profile: 0x0015 (DVD-R/DL sequential recording) Profile: 0x0016 (DVD-R/DL layer jump recording) Profile: 0x0014 (DVD-RW sequential recording) Profile: 0x0013 (DVD-RW restricted overwrite) Profile: 0x001A (DVD+RW) Profile: 0x001B (DVD+R) Profile: 0x002B (DVD+R/DL) Profile: 0x0010 (DVD-ROM) Profile: 0x0009 (CD-R) (current)Profile: 0x000A (CD-RW) Profile: 0x0008 (CD-ROM) Profile: 0x0002 (Removable disk) Using generic SCSI-3/mmc   CD-R/CD-RW driver (mmc_cdr).Driver flags   : MMC-3 SWABAUDIO BURNFREE Supported modes: TAO PACKET SAO SAO/R96P SAO/R96R RAW/R16 RAW/R96P RAW/R96RDrive buf size : 1053696 = 1029 KBBeginning DMA speed test.

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