发明名称 Optical Disc Device
摘要 There is provided an optical disc device capable of recording and reproducing a DVD-RAM disc, which can perform a control with stability at a high speed without being affected by a CAPA component. The optical disc device comprises an error signal detection unit for detecting an error signal from a signal component obtained from an optical pickup, a filter for removing a specific frequency component included in the error signal, a holding unit for temporarily holding the error signal, a switching unit for switching the destination of the error signal to either the filter or the holding unit, a servo control unit for controlling the optical pickup by using the error signal outputted from the filter or the holding unit, and a controller for adaptively controlling the switching timing of the switching unit in accordance with the specific frequency component included in the error signal.
