20090022022 | CYCLIC MEMORY AND DISC DEVICE - Provided is an orbiting memory capable of suppressing residual deviation even when a phase difference is caused between a signal to be compensated and information stored in a memory to be fed back and a disc device using the orbiting memory. The disc device includes: an adder to which a signal (s | 01-22-2009 |
20090052287 | DISC CONTROL DEVICE - To obtain a construction in which unnecessary learning can be avoided and optimal and stable positioning control can be carried out upon introducing a repetition control method in an optical disc device. | 02-26-2009 |
20100149935 | Optical Disc Device - 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. | 06-17-2010 |
