A method, a device, and a computer-readable medium for simulating a multi­layer optical storage medium are disclosed. A multiple-layer optical storage medium is simulated by using a set of multiple single-layer media, wherein the number of multiple single-layer media is equal to or smaller than the number of multiple layers of the multiple­ layer optical storage medium, and each single layer of the set of multiple single-layer media comprises a copy of the corresponding layer of the multiple-layer medium. This is transparent to any application software accessing a device having such a single-layer medium inserted therein by the drive reporting to the application that a multi-layer optical storage medium has actually been inserted into the device for reading or writing. The device may be comprised in an audio-visual player and/or a recorder such as a DVD recorder.
