    摘要： 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.

    摘要： In accordance with the present invention, when a flashing is initiated a flashcode can be uploaded (310) to a flash only area of a reprogrammable non-volatile storage medium. Then, it is verified (320) whether the flashcode has been uploaded correctly to the flash only area. If the flashcode has not been uploaded correctly, the flashcode will be uploaded (310) to the flash only area again. When the flashcode has been uploaded correctly, a code segment of said reprogrammable non-volatile storage medium can be flashed (330) with new code in the next step. Thereafter, it is verified (340) whether the new code has been correctly written into the code segment. If the code was not satisfactorily written into the code segment, the code segment is flashed (330) again.

    摘要翻译： 根据本发明，当启动闪光时，闪光码可以被上传（310）到可重新编程的非易失性存储介质的仅闪光区域。 然后，验证（320）闪光码是否已被正确地上传到仅闪光区域。 如果Flash代码没有正确上传，Flash代码将再次上传（310）到仅限Flash区域。 当闪存已经正确上传时，所述可重编程非易失性存储介质的代码段可以在下一步中用新代码闪存（330）。 之后，验证（340）新代码是否已被正确写入代码段。 如果代码不能令人满意地写入代码段，则代码段再次闪存（330）。

    摘要： A disc drive (1) comprises first clamping means (5) and second clamping means (7) for supporting an optical disc (3) that is to be played in the disc drive (1). Drive means (9) is provided for rotating the optical disc (3) relative to optical means (11) for writing data to, or reading data from, the optical disc (3). The disc drive (1) further comprises a data storage medium (13) for storing data such as embedded software for controlling the operation of the disc drive (1). The data storage medium (13) is permanently located in the disc drive (1), thereby being permanently available for controlling the operation of the disc drive (1). The data storage medium (13) is located coaxially with optical disc (3) that is to be inserted into the disc drive (1) for playback. The data storage medium (13) is also positioned such that, during playback of a normal optical disc (3), the data storage medium is located on the reverse side of the optical disc (13), i.e. the non-optical side of the optical disc (3). In one embodiment the data storage medium is radially smaller than the optical disc (3), while in another embodiment the data storage medium is radially larger than the optical disc (3).
