摘要:
Provided is a tape recorder that has a tape including at least one partition and that controls access to the tape. The tape recorder includes: means for identifying a position of data on the tape; means for sequentially reading necessary data areas in the data; means for sequentially copying the necessary data areas to the beginning of an empty area on the tape; means for creating a continuous front empty area formed of unnecessary data areas and copy source areas of the necessary data areas on the tape; and means for moving a beginning of the partition (BOP) to a position immediately after the front empty area and for updating the position information on the beginning of the partition.
摘要(中):
提供了一种具有包括至少一个分区并且控制对磁带的访问的磁带的磁带录音机。 录像机包括:用于识别磁带上数据位置的装置; 用于顺序读取数据中的必要数据区的装置; 用于将所需数据区顺序复制到磁带上的空白区域的开头的装置; 用于创建由不必要的数据区域形成的连续的前空区域和在磁带上复制必需数据区域的源区域的装置; 以及用于将所述分区(BOP)的开头移动到所述前空区域之后的位置并用于更新所述分区开始处的位置信息的装置。
