    摘要: A region management method for an information recording medium capable of maintaining data interchangeability among devices and preventing malfunction when one information recording medium shared among devices different in type or number of file systems that can be interpreted by devices is provided. A recording region of the information recording medium is divided into a plurality of regions, and region information such as position and size of each region is held in the information recording medium. Different file systems are constructed in individual data recording regions. In response to a command from an information processing apparatus, accessible regions by the information processing apparatus are changed over by, for example, referring to validity flag information that indicates a presently valid region.

    摘要: A file to be read or written is designated and accessed from an access device side to a nonvolatile memory device. In an initialization after start-up of the power source, an empty capacity detector detects empty capacity parameters of a nonvolatile memory with dividing the memory into a plurality of regions. An empty capacity parameter notification part notifies the access device of the empty capacity parameters in a stepwise fashion whenever the empty capacity detector detects an empty capacity. With this, at the time when the empty capacity becomes not less than a capacity required to write file data, the data can be written to the nonvolatile memory without waiting for completion of the initialization, resulting in improvement of a response in the recording.

    摘要: An optical transmission system with automatic startup functions to optimize the power level of optical signals entering each optical amplifier and operate those amplifiers in appropriate mode. In the process of starting up an optical transmission system, upstream and downstream optical transmission devices set up themselves under the coordination of their internal controllers. The downstream device controller adjusts its local variable optical attenuator by utilizing optical noise emission from a post-amplifier in the upstream optical transmission device, and it selects and sets a preamplifier unit to work in appropriate operating mode. The upstream device controller, on the other hand, selects and sets operating mode of its local post-amplifier unit. During this process, the upstream and downstream device controllers exchange messages over supervisory control channels to achieve the purpose.
