Tech Tip:What Is Scms And What Are Its Disadvantages?
SCMS is an acronym for Serial Copy Management System. SCMS is pronounced "scums," a word which accurately reflects how most people in recording feel about it. Some DAT recorders write the SCMS code on the tape in order to prevent the possibility of digitally copying a digital copy. In other words, you can make digital copies of a DAT master, but you can't make any digital copies of a digital copy of that DAT master. SCMS is transmitted through S/PDIF connections, but not through AES/EBU connections. On some DAT recorders it can be disabled. On other DAT recorders, it is absent altogether.
