    • In a method for dynamically managing a digital recording system's bandwidth requirements, accesses to the recording system's hard drive are prioritized according to a pre-defined policy which gives the first priority to the data streams being written to the disk, the second priority to the data streams being read from the disk, and the third priority to other accesses to the disk. The recording system's bandwidth efficiency may also be improved by optimizing allocation of the disk's storage space which is partitioned into lower bandwidth portions and higher bandwidth portions, where lower bandwidth data streams are stored in lower bandwidth portions and higher bandwidth data streams are stored in higher bandwidth portions. The inner portions of the disk are lower bandwidth portions and thus data streams are recorded from the inner diameter outwards to the outer diameter of the disk. A recorded data stream may be migrated from a higher bandwidth portion to a lower bandwidth portion.
    • 在用于动态管理数字记录系统的带宽要求的方法中,对记录系统的硬盘驱动器的访问根据预定义的策略进行优先级,该预定义策略给写入磁盘的数据流赋予第一优先级,数据的第二优先级 流从磁盘读取,第三优先级到其他对磁盘的访问。 记录系统的带宽效率还可以通过优化分配到较低带宽部分和较高带宽部分的盘的存储空间的分配来提高,其中较低带宽数据流存储在较低带宽部分中,并且较高带宽数据流存储在较高带宽 部分。 盘的内部是较低带宽部分,因此数据流从盘的内径向外记录。 记录的数据流可以从较高带宽部分迁移到较低带宽部分。
