    • PROBLEM TO BE SOLVED: To improve performance of writing data with a small block size or file size to a tape cartridge.SOLUTION: A tape cartridge 2 is provided with a magnetic tape 4 and a nonvolatile semiconductor memory 5. A comparison part 11 compares the transmission speed of data that is transmitted from a host machine to a tape drive device 1, with a speed threshold value. A speed determination part 12 determines the speed of writing data to the tape cartridge according to the result of the comparison. A data write part 13 writes data to the magnetic tape 4 provided for the tape cartridge 2 if the transmission speed is faster then the speed threshold value; and writes subsequent data, which follows the data written to the magnetic tape 4, to the nonvolatile semiconductor memory 5 provided for the tape cartridge 2 if the transmission speed is slower than the speed threshold value.
    • 要解决的问题:提高以小块大小或文件大小将数据写入磁带盒的性能。 < P>解决方案:带盒2设置有磁带4和非易失性半导体存储器5.比较部11将从主机发送的数据的传输速度与带驱动装置1的速度进行比较 阈值。 速度确定部分12根据比较结果确定向带盒写入数据的速度。 如果传输速度比速度阈值快,则数据写入部分13将数据写入到用于带盒2的磁带4; 并且如果传输速度比速度阈值慢,则将跟随写入磁带4的数据的后续数据写入到设置在带盒2上的非易失性半导体存储器5。 版权所有(C)2013,JPO&INPIT
