Abstract: A method for arranging conducting lines of a flexible cable in an optical disk drive first confirms the pins having similar functions of all chips on a main board and a sub-board, and uses only one conducting line of the flexible cable to connect these pins. Therefore, the number of the conducting lines of the flexible cable can be reduced.

Abstract: When recording to an optical disk under zoned constant linear velocity (ZCLV) or partial constant angular velocity (PCAV) control, a plurality of super link points are dynamically set in the packet link areas. In this way, packet units recorded on a track of the optical disk are kept continuous.

Abstract: A camcorder includes an interface port, an interface controller and a recorder. The interface port is connected to an external electronic apparatus and transmits data between the external electronic apparatus and the camcorder. The interface controller selects one of the camcorder and the external electronic apparatus to be a host, which outputs a control signal. The recorder records the data to a recording medium according to the control signal.

Abstract: A system and method of operation information collection for CD-ROM drives. The system includes a CD-ROM drive system, a reception device and a computer host. The CD-ROM drive system outputs operation information to the reception device through a serial communication interface according to a start transmission signal. The reception device stores the operation information in storage, and transmits the operation information to the computer host in real time, or selectivity, transmits all received operation information to the computer host at a time according to a trigger, such that he computer host can analyze the operation information and perform related operations.

Abstract: A data writing method is used with an optical recording apparatus to write data into a rewritable disc. For writing data, the optical recording apparatus enters a writing mode and a first packet is written into the rewritable disc. Then, the optical recording apparatus enters a detecting mode and data of the first packet written into the rewritable disc are read for defect detection. If no defect of the first packet is detected in the detecting mode, the writing mode is entered again, so a second packet can be written into the rewritable disc. On the other hand, if a defect of the first packet is detected in the detecting mode, a rewriting mode will be entered and the first packet is rewritten into the rewritable disc again.

Abstract: A method for controlling laser power of an optical recording/reproducing apparatus includes the following steps. Firstly, a writing procedure is performed with an initial electric power level supplied to a laser module of the optical recording/reproducing apparatus. Then, an optimum power calibration (OPC) procedure is performed to determine a first optimum electric power level if a temperature change of the optical recording/reproducing apparatus under the initial electric power level is larger than a threshold value. Afterward, by replacing the initial electric power level with the first optimum electric power level to be supplied to the laser module of the optical recording/reproducing apparatus, the writing procedure is performed.

Abstract: A device and method capable of changing codes of a micro-controller comprises a micro-controller, an address latch, a flash memory, a static random access memory (SRAM), and a logic circuit. The flash memory has a renovation program and a general program recorded therein. The logic circuit can be a logic gate circuit, a programmable logic array, or a field programmable gate array. During a period of changing code, the renovation program of the flash memory controls the micro-controller to copy the renovation program itself into the SRAM and then makes the renovation program recorded in the SRAM control the micro-controller to replace the general program of the flash memory with a new program. Thereby, codes can be renewed without the need of replacing the original flash memory.

Abstract: A method to control the operating speed of computer storage device by determining the transmitting mode of a computer interface. A first speed transmitting mode is used to output a controlling signal to the exterior interface when the transforming interface receives a reset signal provided by the exterior interface. If the transforming interface receives a reply signal provided by the exterior interface, the first speed transmitting mode is switched to a second speed transmitting mode having a slower transmitting speed than the first speed transmitting mode. An ATAPI command is sent to the interface controller by the transforming interface through an interior BUS to dictate allowed transmitting speed to limit the writing speed of the computer storage media.

Abstract: A system to select from among a plurality of devices to host a large-capacity storage interface. The system includes a first interface connector, a second interface connector, and an interface-transforming chip. The first interface connector is coupled to a first BUS cable to access first exterior data. The second interface connector is coupled to a second BUS cable and an interior BUS cable of the large-capacity storage interface to access second exterior data. The interface-transforming chip detects a control signal input to the second interface connector, then selects one of the first interface connector or the second interface connector to host the large-capacity storage interface according to the voltage level of the control signal.
