About any CD, DVD, or BD recorder produced in the recent ten years.
<BR>
<A HREF="http://libburnia-project.org">libburn</A>
supports recorders which are compliant to standards MMC-1 for CD and
MMC-5 for DVD or BD. Linux, FreeBSD, Solaris, and NetBSD allow to access drives
connected via SCSI, PATA (aka IDE, ATA), USB, or SATA.
<BR>

<H2>Software requirements :</H2>
<DL>
<DT>Linux with kernel 2.4 or higher (and libc, of course) :</DT>
<DD>With kernel 2.4 an ATA drive has to be under ide-scsi emulation.</DD>
<DD>With kernel 2.6 or higher the drive should not be under ide-scsi.</DD>
<DT>or FreeBSD (with libc, of course) :</DT>
<DD>ATA and SATA drives need atapicam running.</DD>
<DD>libcam has to be installed.</DD>
<DT>or Solaris (with libc, of course) :</DT>
<DD>Tested on kernel 5.11, hopefully suitable for older ones too.</DD>
<DT>or NetBSD (with libc, of course) :</DT>
<DD>Tested on 6.1.2 and 6.1.3</DD>

<DT>The most common options of cdrecord for data and audio on CD media
are provided in a compatible way.<BR>
On all DVD media, cdrskin is able to perform any recording job
which is possible with cdrecord.
Other than with cdrecord, option -multi is supported with many DVD types and
BD-R. Write mode -tao works with anything but quickly blanked DVD-RW and
DVD-R DL, which both support no -multi.

<CENTER><H3>About the relationship of cdrecord and cdrskin</H3></CENTER>
First of all: this relationship is single sided, as cdrskin has to be aware of
cdrecord but not vice versa.
<BR>
<BR>
I was a long time user of cdrecord and it worked fine for me. 
Especially i do appreciate its write mode -tao which allows to pipe arbitrary
data on CD and CD-RW via stdin. cdrecord is reliable, versatile and well
maintained. So for me - there would be no problem with using it for
burning CDs.
<BR>
But the author of cdrecord and the Linux kernel people foster a very hostile 
relationship. Ok, that's their business, not mine (or ours if you are with me).
One has to be aware, though, that this relationship might lead to a situation
where cdrecord is no longer available for certain Linux kernels.
<BR>
To have my own project prepared for such a time, i began to implement its
cdrecord gestures on top of libburn. 
From now on i invite other interested users of cdrecord to teach cdrskin
the gestures necessary for their cdrecord applications.
Contact me. Let's see what we can achieve.
<BR>
<BR>
libburn and cdrskin are now mature enough to substitute cdrecord in its
major use cases of CD and DVD burning. It is possible to foist cdrskin on
various software packages if it gets falsely named "cdrecord".
I do not encourage this approach, but of course such a replacement
opportunity is the goal of a cdrecord compatibility wrapper.
<BR>
<BR>
It is very important to me that this project is not perceived as hostile
towards Joerg Schilling and his ongoing work.
I owe him much. For cdrecord, for mkisofs, for star. Chapeau.
<BR>
