CD-RW 사용하기 위한 준비과정

 bash# cdrecord -v -eject speed=<RW speed> dev=<Device number> <ISO Image file name> 

위와 같은 형식을 통해 CD를 굽게 되는데 여기서 RW speed는 구입당시 박스나 설명서에 나와있을겁니다.

통상 4라고 하면 무난할듯 하지만 자신의 CDRW에 맞게 사용하세요.

그리고 Device number는 "cdrecord -scanbus" 명령을 통해서 알수 있습니다.

Linux Kernel v2.6에서는 "cdrecord -scanbus -dev=ATA:" 명령으로 방법이 바뀌었습니다.

저의 경우는 다음과 같이 나오는군요.

여기서 예를 들자면 저는 backup.iso를 굽고 싶을때 다음과 같이 하면 되겠네요.



Linux Kernel v2.4 이하 버젼에서

bash# cdrecord -v -eject speed=4 dev=0,0,0 backup.iso 

Linux Kernel v2.6 이상 버젼에서 (dev부분에 직접 device를 지정하는것이 가능해졌습니다.)

bash# cdrecord -v -eject speed=4 dev=/dev/cdrom backup.iso 

그리고 만약 자신이 굽고자 하는 CD매체가 CD-RW라면 먼저 깨끗히 청소하는 작업이 필요한데

cdrecord -v -eject -blank=all speed=4 dev=0,0,0 backup.iso 

이렇게 하시면 CD-RW매체를 청소하고 굽게 됩니다.

하지만 "-blank=all"의 경우는 완전히 소거해주는 것으로 시간이 많이 필요로 합니다. 때문에 "-blank=minimal" 옵션을 사용하시는것으로 시간을 단축할수 있습니다.



참고로 "root" 유저로 하셔야 됩니다. 일반 유저로 CD를 굽기 위해서는 몇가지

확인 사항이 더 있는데 그부분은 각자 해결해보세요.





다음은 Linux Kernel v2.6기준 실행화면입니다. (Fedora Core1 CD1 iso image를 굽는 화면)
