positioning time 定位时间 The time interval required to bring a transducer and the location of the requined data on a data medium into the relative physical position necessary for the data to be read; for example, the time required to position a head on a magnetic disk, that is, seek time plus the time required for the data to arrive at the head, that is, rotational delay. 将传感器以及数据媒体上所需数据单元带到为读取该数据所必须的相对物理位置上所需要的时间间隔,例如磁盘上磁头定位所需 时间(即寻道时间)加上数据到达磁头处所需时间(即旋转延迟时间)。 |
