SafeLock is a program of Polish authorship that allows you to create secured Data CDs, Audio CDs, as well as to protect video files in AVI format. The program protects CDs with five methods: it introduces EFM correction, identifies the Q-subchannel, which improves CD security, reads ATIP information (manufacturer's CD information, capacity) in the writer, checks the presence of the wrong sector at the end of the CD, checks the presence of the PreGape key.
