    摘要： A computer system includes a host computer and a peripheral memory device such as a CD ROM which are interconnected by a bus including a plurality of pipes defined by packets, time division multiplexing, frequency division multiplexing, or code division multiplexing. A plurality of pipe configuration registers are maintained for controlling bus configuration. A BUS controller for the bus includes a plurality of registers for controlling data transfer including pipe data flow direction, packet size, control information, bandwidth setting, and descriptor pointer. The plurality of pipes can have different bandwidths and latencies to efficiently facilitate the transfer of commands, data, and control information. The peripheral memory device is able to transfer and receive data directly to and from the host computer using a dedicated pipe without the need of a buffer memory at the peripheral device.

    摘要： A method comprises writing data to a disk using a write laser, and halting recording at a stopping point, prior to an end of the disk. The method further comprises reading the data recorded on the disk and evaluating the data. The method further comprises adjusting the characteristics of the write laser, if appropriate, and restarting the writing using the adjusted characteristics for the write laser.
