摘要： A modulation device and a demodulation device suitably performing DSV control while reducing the size and lowering the price of the hardware. Recording data is modulated at a modulator. In a DSV calculator, the DSV value of a modulated data is calculated in units of 1 DSV frame. A comparator outputs a sign comparison result of a DSV value cumulatively added from the start of recording and a DSV value to a DSV control bit insertion unit. The DSV control bit insertion unit inserts bits of DSV control data in accordance with the comparison result at a predetermined insertion position of the modulated data delayed by exactly an amount of 1 DSV frame. Thereafter, the modulated data is subjected to NRZ modulation.

摘要： A data access controller has an SRAM adapted to hold two ECC blocks so that the SRAM is used efficiently for multiple kinds of processes. At playback of data, writing of ECC block A from a demodulator and an ECC process for ECC block B begin simultaneously. When the ECC process ends, release of the ECC block B to the outside begins. When the writing of ECC block A ends, the ECC process for the ECC block A begins and, at the same time, writing of ECC block B from the demodulator begins.

摘要： The present invention relates to an optical recording method for recording data on an optical disc by using a laser beam. When the optical disc is inserted into an optical recording device (step S1), a test writing area PCA (Power Calibration Area) that can be used for an OPC (Optimum Power Calibration) on the optical disc is searched and an optical pickup is allowed to stand by at that position (step S4). Then, when an input of a recording operation of data is received (step S6), an OPC operation is carried out at the stand-by position (step S7). After an optimum power is obtained, the optical pickup is moved to a data recording area on the optical disc (step S10) to record the data in the data recording area of the optical disc by the optical pickup (step S11).

摘要： The present invention relates to an information processing apparatus wherein a device connected to a host computer enters a sleep mode in accordance with a judgment made by the device itself, and the device is restored to its original operating state by a hardware reset signal received from the host computer. To put it in detail, if no data is exchanged through an ATAPI command data I/F for at least a predetermined period of time, a CPU of the device outputs a sleep mode to a clock generator and a drive power supply block to put the device in a sleep mode. When a CPU of the host computer outputs a HRST signal in this mode to the device through an ATAPI bus to restore the device from the sleep mode, an IRQ signal reception unit of the CPU employed in the device receives this HRST signal. Receiving the HRST signal, the CPU of the device issues a command requesting restoration from the sleep mode to the clock generator and the drive power supply block. The present invention can be applied to an optical disc drive.
摘要翻译：信息处理装置技术领域本发明涉及一种信息处理装置，其中连接到主计算机的装置根据装置本身的判断进入睡眠模式，并且通过从所述装置本身接收到的硬件复位信号将装置恢复到其原始操作状态主机。详细地说，如果在ATAPI命令数据I / F中没有数据交换至少预定时间段，则设备的CPU将休眠模式输出到时钟发生器和驱动电源块，以将设备处于睡眠模式。当主计算机的CPU通过ATAPI总线将该模式的HRST信号输出到设备以将设备从睡眠模式恢复时，设备中使用的CPU的IRQ信号接收单元接收该HRST信号。接收到HRST信号后，设备的CPU发出请求从休眠模式恢复到时钟发生器和驱动器电源模块的命令。本发明可以应用于光盘驱动器。
