durability index
耐用率［指数］
A measure of the durability of a tape expressed as the number of passes that can be made before a significant degradation of output occurs, divided by the corresponding number that can be made using reference tape. Measurements are made by shuttling a given length back and forth over a transport and monitoring the dropout count and／or decrease in output
对磁带耐用性的一种度量,表示为在输出信号没有明显衰减时磁带穿过磁头的次数与参 考带穿过磁头次数的比。通过在一个传送装置上来回反复地转动一段给定长度的磁带,记录 输出信号丢失的次数和／或减弱的次数来测量磁带的耐用率。 |
