    • A optical storage disk provides multiple logical disks without the need to physically alter the structure of the optical storage disk. According to one example embodiment of the present invention, a dual-layer data disk is adapted to store data in each of two layers readable by an optical disk reader. A first region of the disk includes data recorded for a first logical disk, and a second region is adapted to store data for a second logical disk, and the first and second regions are located on the two layers. Each of the data logical disks includes a lead-in region and a lead-out region and for data therebetween traversing each of the two layers. The lead-out region of the first logical disk stores pointing data which points to the lead-in region of second logical disk, and the logical disks are not necessarily physically contiguous.
    • 光学存储盘提供多个逻辑磁盘,而不需要物理地改变光学存储盘的结构。 根据本发明的一个示例实施例,双层数据盘适于在光盘读取器可读取的两层中存储数据。 磁盘的第一区域包括为第一逻辑磁盘记录的数据,第二区域适于存储第二逻辑磁盘的数据,并且第一和第二区域位于两个层上。 每个数据逻辑磁盘包括导入区和导出区,并且其间横跨两个层中的每一个的数据。 第一逻辑磁盘的导出区域存储指向第二逻辑磁盘的导入区域的指向数据,并且逻辑磁盘不一定在物理上相邻。

    • To minimize the time and resources typically associated with collision detection in a single channel communications system, this invention provides a method and apparatus for a collision based protocol that assures that one device in the system always wins a collision conflict. A device in accordance with this invention that is assured of always winning a collision conflict need not contain a collision detector, nor the storage resources typically used to buffer the effects of a collision. The device is also always assured of continuous transmission access once its transmission begins. This continuous transmission access is particularly well suited for high speed data access devices such as magnetic disks, laser discs, and the like, that access data continually as the disk passes by their read heads.
    • 为了最小化在单个信道通信系统中通常与冲突检测相关联的时间和资源,本发明提供了一种用于基于冲突的协议的方法和装置,其确保系统中的一个设备总是赢得冲突冲突。 确保始终赢得冲突冲突的根据本发明的装置不需要包含冲突检测器,也不包含通常用于缓冲冲突效应的存储资源。 一旦传输开始,该设备也始终保证连续传输接入。 这种连续传输接入特别适用于高速数据存取设备,如磁盘,激光盘等,当磁盘通过读头读取磁盘时,可以连续访问数据。

    • To maximize the throughput and minimize the latency associated with communications among devices on a single channel communications system, this invention provides a method and apparatus for a fairness based protocol that assures each device an equal opportunity to access the single channel communications system. The protocol forces a “fairness” delay between each sequential transmission from a device, thereby allowing another device to gain access to the communications channel during this fairness delay period. In a preferred embodiment, the duration of each transmission is limited, thereby providing a maximum latency period for a device to gain access to the communications channel, and a minimum bandwidth allocation to the device. By providing a protocol having a guaranteed minimum bandwidth and maximum latency, a device in accordance with this invention need only contain the storage resources needed for the latency period.
    • 为了最大化吞吐量并最小化与单个信道通信系统上的设备之间的通信相关联的延迟,本发明提供了一种用于基于公平的协议的方法和装置,其确保每个设备具有访问单个信道通信系统的相等机会。 该协议强制来自设备的每个顺序传输之间的“公平”延迟,从而允许另一设备在该公平延迟周期期间访问通信信道。 在优选实施例中,每个传输的持续时间被限制,从而为设备提供访问通信信道的最大等待时间周期,以及对设备的最小带宽分配。 通过提供具有保证的最小带宽和最大延迟的协议,根据本发明的设备仅需要包含等待时间段所需的存储资源。
