What best DVD-R or DVD+R?

The DVD-R format was developed by Pioneer in 1997 vc DVD+R in 2002 by Sony.

DVD+R format was not an official DVD format until January 25, 2008.

DVD-R(W) and DVD+R(W) format are incompatible.

DVD-R(W) use amplitude modulation, DVD+R(W) use phase modulation, so more reliable.

On multi-session DVD-R(W) disk any session take up to 96 MB in time on DVD+R(W) every session take exactly 2 MB.

DVD+R(W) win!

How many times can I rewrite to a CD-RW?

A CD-RW disc can be erased and rewritten up to a 1,000 times. Reliability and performance will not decrease, even as the number of rewrites increase.

Make an ISO image

$ dd if=/dev/dvd of=dvd.iso  # for dvd
$ dd if=/dev/cdrom of=cd.iso # for cdrom
$ dd if=/dev/scd0 of=cd.iso  # if cdrom is scsi

$ mkisofs -o /tmp/cd.iso /tmp/directory/ # from file hierarchy

Burning tools

** cdrtools.

In 2006 build system of cdrtools changed and have CDDL, which incomputable with GPL.

See

http://cdrecord.berlios.de/private/cdrecord.html http://en.wikipedia.org/wiki/Cdrecord

** cdrkit.

Fully GPL alternative for cdrtools. Includes:

  • wodim (an acronym for write optical disk media), which was forked from the cdrecord program in cdrtools.
  • icedax (an acronym for incredible digital audio extractor), which was forked from the cdda2wav program in cdrtools.
  • genisoimage (short for generate ISO image), which was forked from the mkisofs program in cdrtools.

See

http://www.cdrkit.org/ http://en.wikipedia.org/wiki/Cdrkit

Installing under Debian:

$ sudo apt-get install wodim genisoimage

Cygwin (cdrecord is symlink to wodim, mkisofs is symlink to genisoimage, cdrkit contain only READMY):

$ setup.exe -p cdrkit,wodim,genisoimage

Make iso image:

$ genisoimage -A "<info>" -gui -J -R -o <img-file> <dir1> <dir2> ...

<info> is up to 128 bytes. -J adds Joliet directory records wich useful on Windows. -R adds the Rock Ridge protocol.

To test your image mount it (on Linux):

$ sudo mount -t iso9660 -o loop,ro <img-file> <mnt-point>

Burn iso image

xorriso

xorriso copies file objects from POSIX compliant filesystems into Rock Ridge enhanced ISO 9660 filesystems and allows session-wise manipulation of such filesystems. It can load the management information of existing ISO images and it writes the session results to optical media or to filesystem objects.

Vice versa xorriso is able to restore file objects from ISO 9660 filesystems.
