1.3 W ( oqĶ )

   CD-ROM stands for Compact Disc Read Only Memory, a storage medium
   utilizing an optical laser to sense microscopic pits on a silver
   shimmering disk. The silver shimmering comes from an aluminized layer
   which is the carrier. The pits represent the bits of the information
   (in some way) and are so petite that some billions of them fit on the
   disc. Thus a CD is a mass-storage medium.

   The term CD-R is a short form of CD-ROM recordable and refers to a CD
   that doesn't have those "microscopic pits" on it's surface. Thus it's
   empty. Instead of the silver aluminium layer a CD-R has a special film
   (colored) into which "microscopic pits" can be burned in. This is done
   by giving the laser which normally only senses the pits a little bit
   more power so he burns the pits. This action can only be taken once on
   a CD-R, although you can leave out some areas for later writing,
   creating a so called multi-session CD.

   The CD-ROM rewritable (short: CD-RW) was developed to come around the
   limitation of CD-R media. Here the laser can not even burn pits into
   the media, but it can also melt the media back into it's original
   state. This is possible, because the laser does not really burn holes
   into the media - you do not see a puff of smoke while burning and no
   voice from above tells you "target destroyed". What the laser really
   does is to trigger a phase change, thus the name "phase change
   devices" for CD-RW-writers. An example for a very similar technique
   used in daily life is the cleaning car in an ice-hockey stadion:
   during the pauses of the game, the car drives over the ice and fills
   the scratches in the ice (-> bits containing some sort of information
   about the game... hehehe) with melted splinter.

   This HOWTO deals with the task of writing CD-Rs and CD-RWs. Welcome on
   board, captain.

   Instead of writing a true audio-CD, you can optionally convert your
   wav-audio-files into mp3-audio-files and store them on a ISO-9660
   filesystem as regular files. Usually MPEG III gives you a compression
   of 1:10.

   Of course, most CD-players are not able to read files... this is the
   drawback. On the other hand, why not running the music for your next
   party from harddisk? 18 Gbyte are enough for 3000-4000 titles. :-)

   A software MPEG III-encoder is available from

     [18]http://www.stud.ifi.uio.no/~larsi/other/8hz-mp3-cheng.tar.gz

     [19]http://homepages.uni-tuebingen.de/student/michael.hipp/mpg123/

   For recorded speech, you may want to try to reduce its size using
   shorten or "GSM lossy speech compression":

4.11 "How to make bootable CD-ROMs?"

   You must have an 1.44 MB bootable floppy-disk. Create an exact image
   of this floppy-disk by issuing the command

dd if=/dev/fd0 of=boot.img bs=18k

   Place this floppy-image into the directory holding the collection of
   your files (or into a subdirectory of it, just as you like). Tell
   mkisofs about this file with the option '-b' and also use '-c'. For
   details read the file README.eltorito in the mkisofs-distribution.

   An interesting application for a custom bootable CD is as a virus-safe
   DOS- or Windows-system. It saves you the money for the harddisks (if
   you have a network and use samba to put the user-data on a
   fileserver). However, this is purely theoretical as nobody reported an
   actual recipe to me.

   Some details about the bootable RedHat CD-ROM is available from [22]
   http://www.channel1.com/users/rodsmith/rhjol-technical.html.

4.12 "How to make CD-ROMs writable somehow?"

   There is an overlay-filesystem available for Linux, which is mounted
   over the CD-ROM and intercepts all writing operations. New and
   modified files are stored elsewhere, but for the user it looks like
   the CD-ROM is modified. For more information, see [23]
   http://home.att.net/~artnaseef/ovlfs/ovlfs.html.

   If that is not enough for your needs: wait for the UDF-filesystem to
   be supported by Linux or help developing it (see [24]
   http://trylinux.com/projects/udf/.

4.13 "Is it possible to use several writers at once?"

   Yes. However, it has been only tested with two writers yet. And you
   need a kernel patch for more buffers in the SCSI-generic driver ( [25]
   ftp://ftp.fokus.gmd.de/pub/unix/cdrecord/alpha).

4.14 "Which media is the best?"

   The german computer magazine "c't" had a list of tips regarding the
   blank CD-Rs in their november 1996 issue:

     * "No-name" discs are generally not of highest quality and should
       better not be used.
     * If a recordable CD is defective, this is likely to apply to the
       whole batch (if you bought more than one at a time); maybe you are
       lucky and can at least use the first 500MB of such CD-Rs ...
     * Don't touch the CD-Rs at their shimmering side before writing.

5. DѨM

   Always remember, that you can still use corrupt CD-ROMs as coasters.

   If it works under the other operating system and you use loadlin to
   boot Linux, then that is your problem. Loadlin makes a warm-boot with
   most of the hardware already initialized and that confuses the
   Linux-kernel.

5.2 Error-message: No read access for 'dev=2,0'.

   Under Linux, some versions of the C-library are incompatible (buggy),
   so that an application linked against one version will not work with
   another. An example for an error triggered by pre-compiled binaries is
   the following:

[root@Blue /dev]# cdrecord -eject dev=2,0
cdrecord: No such file or directory. No read access for 'dev=2,0'.
