Abstract: The present invention provides an improved file system format for an optical disc to help prevent illegal copying of multimedia content, where certain non-readable data record is placed into increased measured length of a multimedia data block; disc made pursuant to present format allows normal playback with very low level noise that would not affect the user enjoyment of viewing/listening the movie or music content on the multimedia disc.

Abstract: An optic disc writer device is an embedded type independent system. It has a host controller, a disc writer assembly, and a printer assembly. The disc writer assembly is electrically connected to the host controller and has a robotic arm, at least one disc writer, and an optic disc deposition zone. The robotic arm is operated to move to the optic disc deposition zone for picking and/or depositing an optic disc and to move the optic disc to the disc writer by which a writing operation is performed on the disc to provide a writing-completed disc. The printer assembly is electrically connected to the host controller. The printer assembly includes a disc tray that is controlled by the host controller for extension and withdrawal for receiving the writing-completed disc therein. The printer assembly is operated to form printing of patterns on a surface of the writing-completed disc.

Abstract: The present invention provides a data transmission device with high speed serial transmission interfaces and control method thereof, and includes a control unit, at least one first storage device connected to the control unit and at least one second storage device, at least one switching device, which is used to switch data transmission lines; each of the switching devices being connected to the control unit, the second storage device and a computer. Accordingly, the switching devices enable the storage devices to connect to the computer to implement data transmission, or the switching devices switch connection to form an independently operable data transmission control system to enable implementing data transmission between the storage devices. Moreover, an automatic detection mode and a manual mode can be used to control connection to the computer or enable independent operation of the data transmission device.
