In addition to the possible inability for some CD players to read a DualDisc properly, other consumer criticisms of DualDisc include:
The 1.5 mm-thick disc can get jammed in a very small number of computer DVD drives, DVD players, slot-loading CD players (such as car CD players) and mega-changers. This may even damage the disc.
For any CD player, the thinner CD layer makes reading the CD side of a DualDisc harder than reading a conventional CD. Thus, anomalies such as small scratches, fingerprints or disc tilt may cause tracking errors more easily than those same anomalies would on a conventional CD. Since disc damage is inevitable over time, this can mean a reduction in a DualDisc's effective lifetime as compared to a CD.
The recommended 60-minute limit of the CD side prohibits it from including the entire content of some conventional CDs.
Since both sides of the disc are used for data, a label cannot appear on either side of the disc. The only way that a consumer knows which side is CD and which is DVD is by looking at the center ring of the disc where it is marked.
