摘要： A disc driving apparatus and an information readout method according to the present invention realize optimum servo control of a readout unit in reading out the information from a recording medium having lands and grooves. The disc driving apparatus includes a unit for correcting tracking error signals, a unit for inverting signals corrected by the correcting unit to generate inverted tracking error signals, a unit for detecting which of the lands and the grooves the readout unit is scanning, and a unit for selecting the tracking error signals or the inverted tracking error signals according to the results of detection by the detection unit to tracking-control the readout unit by the selected signals.
摘要翻译：根据本发明的盘驱动装置和信息读出方法在从具有槽脊和槽的记录介质读出信息的同时实现读出单元的最佳伺服控制。盘驱动装置包括用于校正跟踪误差信号的单元，用于反转由校正单元校正的信号以产生反向跟踪误差信号的单元，用于检测读出单元正在扫描的区域和沟槽中的哪一个的单元，以及单元用于根据检测单元的检测结果来选择跟踪误差信号或反向跟踪误差信号，以通过所选择的信号对读出单元进行跟踪控制。
