摘要： A playback device reads a BD-J application from a BD-ROM and runs the BD-J application. The BD-J application causes, by using a socket connection API, the digital copy module of the playback device to execute copying of a protected content for portable terminals to a removable recording medium and setting of a resume playback point on the copied content. The resume playback point is specified by the BD-J application according to playback time information read from the PSR set.
摘要翻译：播放装置从BD-ROM读取BD-J应用程序并运行BD-J应用程序。 BD-J应用程序通过使用套接字连接API使得播放设备的数字复制模块执行将便携式终端的受保护内容复制到可移动记录介质上，并且在复制内容上设置恢复播放点。恢复播放点由BD-J应用根据从PSR集读取的播放时间信息指定。

摘要： An object lens actuator can improve workability and operate with high reliability by prevention of damage to the object lens actuator and a disc and sticking of a moving part caused by an excessive movement of the moving part. In a disc drive employing the object lens actuation, stable writing/reading operation is implemented by always keeping a focal point of an object lens at a predetermined track of a recording surface of the disc even when being under the action of external perturbations such as a vertical deviation or a radial deviation of the disc, resulting in improved reliability. A solder-flux adhesion prevention gadget is provided between a substrate and a stopper receiving face, which may include a stepped stage, a partition protruding from the surface of the lens holder, or alternatively a combination of them arranged in order in the range.

摘要： An objective lens actuator, being suitable for a thin-sized optical pickup and a thin-sized optical disc apparatus, comprises: an objective lens for focusing a light upon a recording surface of an optical disc; and a driving means including a focusing coil, tracking coils, and a magnetic circuit, for operating the objective lens into a focusing direction of approaching/receding to/from the optical disc, and into a tracking direction of a radius of the optical disc, wherein the magnetic circuit has two (2) pieces of magnets putting the objective lens therebetween, and one of the magnets is short of length in the focusing direction and is long in length in the tracking direction, comparing to the other magnet, thereby brining an unnecessary moment, which is applied upon a moving part including the objective lens therein, to be small, and suppressing inclination or tile and vibration of the objective lens, so as to deal with high-density and high-speed recording/reproducing of information.
