CD-R에 쓰려고 하는 733MiB ISO 이미지가 있습니다. 나는 서로 다른 제조사의 두 개의 CD-R을 가지고 있습니다. 첫 번째 CD-R 디스크(TDK)에서는 굽기 프로세스가 실패하지만 두 번째 CD-R(EMTEC)에서는 성공합니다. 불태우라는 명령은wodim -v speed=1 dev='/dev/scd0' -sao -overburn /home/martin/Downloads/linux.iso

오버버닝 기능은 CD-R/CD-RW 핀아웃 크기에만 의존합니까? 또한 어떤 아이디어라도"낮은 베타 카테고리(B-)(4)"그리고"하이베타 카테고리(A+)(3)"CD-R ATIP 정보 섹션은 무엇을 의미합니까?
답변1
원래 CD 데이터 저장 크기는 650MiB입니다. 동일한 공간에 넣을 수 있는 오디오 데이터의 양 때문에 74분 CD라고도 합니다. CD-R을 사용할 수 있게 된 후 700MiB(또는 80분)의 CD-R이 표시되기 시작했습니다. 오늘날 판매되는 대부분의 CD-R은 이러한 최신 유형입니다.
저는 733MiB를 담을 수 있는 CD-R을 본 적이 없습니다.“CD-R”에 대한 Amazon 검색 결과의 첫 페이지그다지 크지는 않은 것 같습니다.
어쩌면 이 이미지가 화상을 입게 된 것은 단지 순전히 운이 좋았을 수도 있습니다. 아니면 전혀 굽지 않을 수도 있습니다. 운영 체제 설치 프로그램에 미디어 확인 기능이 있는 경우 오버버닝된 디스크에서 처음 설치할 때 반드시 이 기능을 사용해야 합니다.
CD-R에서는 이미지가 전혀 작동하지 않을 수 있습니다. ISO CD 형식은 최근 USB 키 이미지에 널리 사용됩니다. 비슷한 도구가 있습니다UNet 런처이러한 목적을 위한 것입니다.

Warren Young은 2013년에는 이 사실을 몰랐을 수도 있지만 Mediarange는 90분 분량의 음악(800MB) 또는 100분 분량의 음악(900MB)을 수용하도록 설계된 CD-R 디스크를 만들지만 굽기 소프트웨어에서 특별한 오버버닝 기능을 사용해야 합니다. 과거에는 Nero가 인기 있는 소프트웨어였습니다.
이제 2019년에 나는 새 컴퓨터를 설정하면서 이전과 동일한 소프트웨어를 찾으면서 음악을 CD-R 디스크에 구워서 자동차 눈썹에서 사용하고 싶은 방법을 설명하면서 움츠러들었습니다. 사람들은 USB 플래시 드라이브를 꺼내거나 모바일 인터넷을 통해 음악을 스트리밍해야 한다고 제안했습니다.
글쎄, 그렇게 해봤는데 전원을 끄면 엔진을 시동만 걸어도 자동차에 있는 USB 메모리에서 내가 듣고 있는 앨범의 트랙이 손실됩니다. 모바일 인터넷 비용은 제가 반년 동안 선불폰을 사는데 쓰는 10유로보다 더 비쌉니다. 그러니 원하시면 저를 옛날 방식으로 부르세요. 하지만 제 자유 선택을 존중해 주세요! ;-)
