Next, the photo detector receives the reflective beam to generate plural photo-detecting signals received by the auto gain controller to generate a first control signal and a second control signal. Then, the servo controller generates a third control signal according to the first and the second control signals. The objective lens is moved according to the third control signal. Lastly, the photo detector receives the reflective beam to generate plural calibrated photo-detecting signals whereby a wobble signal is generated.

摘要： The present invention discloses a method for controlling a pick-up head during a long seek. During a long seek, a bias voltage is applied to the pick-up head to overcome the inertia of the pick-up head and to prevent the pick-up head from oscillating. This makes it easier for the optical drive to execute the track-on action after a long seek.

摘要： In a layer jump and focusing control method, a first focusing error signal is generated according to the differential astigmatism method in a closed-loop focusing control manner when focusing on the first recording layer. A second focusing error signal is generated according to the astigmatic method in an open-loop focusing control manner when a first layer-jumping procedure is performed to shift a focusing position from the first recording layer to the second recording layer. Then, the completion of the first layer-jumping procedure is determined according to the second focusing error signal, for example when the second focusing error signal passes the zero crossing point and exceeds a threshold level. Afterwards, a third focusing error signal is generated according to the differential astigmatism method in a closed-loop focusing control manner when focusing on the second recording layer.

摘要： A method of on-line adjusting a sled motor control signal (FMO) is disclosed. First, a predetermined FMO is assigned to move a sled for seeking, and a photo signal is monitored. The number of waveforms appearing in the photo signal and a distance from an optical pickup to a target track are calculated under this predetermined FMO. Then, the optical pickup is moved to the target track such that the optical pickup after seeking is located at a center position of a movable range. If the number of waveforms appearing in the photo signal is not equal to a predetermined number, the duration of the FMO is adjusted according to the difference therebetween.

摘要： A method for detecting an unbalanced disc in a disc reading apparatus includes the following steps. Firstly, a disc is loaded into the disc reading apparatus. Then, a start-up procedure is performed at a first rotating speed. After the start-up procedure is completed, the disc reading apparatus enters a ready-to-read state. In the ready-to-read state, an unbalanced disc detection procedure is performed by detecting a vibration degree of the disc at a second rotating speed greater than the first rotating speed. Afterward, it is determined whether the disc is an unbalanced disc according to the vibration degree of the disc.
