摘要： An optical disc drive (ODD) includes a radio-frequency identification (RFID) reader. The reader includes a circuit and a coil antenna which has a rotational symmetry with respect to a rotation axis of a motor, shaft and turntable of the ODD. The coil antenna can be secured to a wall of a housing of the ODD or around the motor and/or shaft. The reader can read an RFID tag on an optical disc. The RFID tag includes a circuit and a coil antenna which has a rotational symmetry with respect to the disc. As a result, the RFID tag can be read while the disc is rotating. A magnetic insulating material such as a ferrite polymer composite film is used to magnetically insulate the coil antenna. An authentication code can be read from the RFID tag to control access to content of the optical disc.

摘要： 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.
摘要翻译：光盘驱动器（ODD）包括一个或多个传感器，其检测用户将盘放置在加载路径中。作为响应，即使在盘向着转盘移动的过程中也触发了用于感测盘的保护层的厚度的过程。可以基于厚度来确定盘的类型（例如CD，DVD或Blu-ray）的初始确定并报告给主计算设备。主机依次决定基于光盘类型加载的应用程序。应用程序的加载可以比ODD等待直到光盘安装在转盘上以检测光盘类型的时间早。可以在光盘就座时进行光盘类型的最终确定。主办方知道初始确定与最终确定之间是否存在分歧。
