Despite claims to the contrary, only Sonic Solutions' "Sonic System" software was able to generate PreMaster CDs. PMCDs were subsequently obsoleted by the more modern and generalized DDP specification. Several factors led to the decline of the PreMaster CD standard. First, the CD-R mechanisms that were able to read and write the hidden cue sheet metadata went out of production in the late 1990s. Second, only Laser Beam Recorders or LBRs manufactured by Sony were able to read PMCDs, which limited the formats adoption by replicators.
Many CD replicators now accept regular
audio data on these discs is not as extensive as what is used for CD-ROM or DVD formats so, corruption of the audio data during readout due to dirt or mechanical damage could result in total loss of the audio data. Modern, professional pre-mastering software relies on the DDP format
, which protects both the audio data and its associated metadata.
