Abstract: An optical disc drive (ODD) includes one or more sensors which detect a user placing a disc in the loading path. In response, a process is triggered for sensing the thickness of a protective layer of the disc even while the disc is moving toward a turntable. An initial determination of the type of the disc (e.g. CD, DVD or Blu-ray®) can be determined based on the thickness and reported to a host computing device. The host, in turn, determines an application to load based on the disc type. The loading of the application can begin sooner than if the ODD waited until the disc was seated on the turntable to detect the disc type. A final determination of the disc type can be made while the disc is seated as well. The host is informed if there is a disagreement between the initial determination and the final determination.

Furthermore, in accordance with this disclosure, a hard coat layer is also formed over the replicated side of the media in order to provide mechanical integrity to the media. Printable layers, printed layers, lacquer, or other materials may also be added. The elimination of the non-information bearing “dummy” substrate can reduce raw materials, thereby reducing costs and providing a more environmentally friendly optical disk. The hard coat can provide the mechanical protection to the replicated side of the 0.
