定位控制设备和盘设备
摘要：
本发明提供一种用于缩短计算延迟时间的定位控制设备和盘设备。盘设备的微控制器在检测到来自解调电路的位置信号时计算位置误差，并且在计算控制量之后，执行确定及校正处理。将开始计算之前的变量值存储在存储器的保留区域(或者保留存储器)中，使得当由于确定及校正处理而要重置变量值时，从保留区域读取变量值，将重置的变量值存储在存储器的改写区域(或者改写存储器)中，并且重新执行对控制量的计算。
摘要（英）：

The present invention provides a positioning control device and a disk device for shortening a calculation delay time. Upon detection of a position signal from a demodulation circuit (51), an MCU (52) of the disk device calculates a position error, and following calculation of a control amount, executes determination and correction processing. A variable value prior to the start of calculation is stored in a save area (MEMORY B) of a memory (or a save memory) such that when the variable value is to be reset as a result of the determination and correction processing, the variable value is read from the save area, the reset variable value is stored in an overwrite area (MEMORY A) of the memory (or an overwrite memory), and calculation of the control amount is re-executed.
