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： A check valve is housed in a valve chamber and includes a support portion and a flexible portion. The support portion extends along a principal axis thereof. The flexible portion is supported by the support portion in a manner extending from the principal axis. A diaphragm defines a lower wall of the valve chamber, and includes an inflow port for fluid at a position that is closed with the flexible portion when the flexible portion is displaced. A bottom plate defines an upper wall of the valve chamber, and faces the diaphragm with the flexible portion arranged therebetween. An uneven portion is provided in at least one of mutually facing areas of an upper principal surface, which is one of two principal surfaces of the flexible portion and faces the bottom plate, and a lower principal surface of the bottom plate, the uneven portion being partially uneven.

摘要： The present invention provides an object lens actuator in which a tilt of an object lens due to a change of an ambient temperature is inhibited even when a metal member is attached to a resin based securing part. It is desirable to improve quality of writing and playing in a disc drive using the object lens actuator. This is achieved by coupling a metal member having a flat portion and bent portions to a securing part near top ends of the bent portions. The flat portion has a normal in the focusing direction. The bent portions extend in the focusing direction from the respective ends of the flat portion in the tracking direction. The securing part has an opening therethrough in the focusing direction, and in the opening, the metal member and the securing part may be coupled between each outermost two support members in the focusing direction.
