An optical disc system jointly developed by Philips (Netherlands) and Sony. Its official name is "Compact Disc." The 12cm diameter CD-DA (normal CD for audio only), 8cm CD Single, and 12cm CD Graphics (digital still images + digital audio) are part of the AV (audio/visual) family, while the CD-ROM is part of the information family. These are playback systems, but there are recordable CDs such as CD-R (for one-time recording) and CD-RW (for repeated recording). Music CDs remain the king of music media, even with the emergence of next-generation music media such as SACD (Super Audio CD) and DVD-Audio. The reason for their survival is that they have no copy protection function, can be copied to a computer, and can be imported into a portable music player.

フィリップス社(オランダ)とソニーの共同開発による光学ディスクシステム。「コンパクト・ディスク」が正式名。直径12cmのCD-DA(音声専用の通常のCD)、8cmのCDシングル、12cmのCDグラフィックス(デジタルの静止映像+デジタル音声)などがAV(音響・映像)系のファミリーで、CD-ROMは情報系のファミリー。これらは再生用のシステムだが、記録用CDとしてCD-R(1回限りの記録用)、CD-RW(繰り返し記録用)がある。音楽用CDは、SACD(Super Audio CD)、DVD-Audioの次世代音楽メディアが登場しても、変わらず音楽用メディアの王座をキープしている。コピープロテクション機能がなく、パソコンにコピー可能で、携帯音楽プレーヤーに取り込むことができるのが、サバイバルの要因だ。
