    • A relative-position measuring system of a recording-medium library apparatus including first to third reference flags installed for measuring the magnitude of the gradient of an accessor and a plurality of relative-position flags provided at a cell drum. A flag sensor for detecting the first to third reference flags is installed on a hand mechanism of the accessor for finding the gradients of the accessor with respect to Y and Z axes. The gradients of the accessor with respect to Y and Z axes are used for correcting design tachometer count values of the relative-position flags to give theoretical tachometer count values which are stored in a memory unit. When the accessor is moved, the relative-position flags are sensed by the flag sensor. Actual tachometer count values which are actually obtained when the relative-position flags are detected by the flag sensor are also stored in the memory unit. Then, difference data between the theoretical tachometer count values and the actual tachometer count values is calculated and stored in the memory unit as well.
    • 一种记录介质库装置的相对位置测量系统,包括安装用于测量存取器的梯度的大小的第一至第三参考标记以及设置在单元鼓上的多个相对位置标志。 用于检测第一至第三参考标记的标志传感器安装在存取器的手持机构中,用于找到存取器相对于Y轴和Z轴的梯度。 存取器相对于Y轴和Z轴的梯度用于校正相对位置标志的设计转速计数值,以给出存储在存储器单元中的理论转速计计数值。 当存取器移动时,相对位置标志由标志传感器感测。 当标志传感器检测到相对位置标志时实际获得的实际转速计数值也存储在存储器单元中。 然后,计算理论转速计计数值和实际转速计计数值之间的差数据并将其存储在存储器单元中。
