摘要： The present invention discloses a method of improving seeking precision by adjusting the track to photo ratio in an optical disc drive. After a disk is tray in, the number of photos detected by the optical disk drive is pre-calculated when the optical pickup module is to seek a predetermined number of tracks. The actual number of seeking tracks performed by the optical pickup module is calculated after the optical disk drive has detected the pre-calculated number of photos. Thereafter an optimal track to photo ratio is obtained.

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： The present invention discloses a method of detecting orientation of an optical disk drive. Firstly, a first moving distance is measured by using a first force driven on a movable optical pick up head of the optical disk drive for a preset period. Next, a second moving distance is measured by using a second force driven on the movable optical pick up head for the preset period, wherein the second force and the first force have opposite direction but the same amplitude. Next, it is determined that the optical disk drive is horizontal orientation when the difference between the first and second moving distances falls within a pre-determined value. Additionally, a first moving time is measured by using a first force driven on a movable optical pick up head for a pre-determined distance. Then, a second moving distance is measured by using a second force driven on the movable optical pick up head for the pre-determined distance, wherein the second force and the first force have opposite direction but the same amplitude. Next, when the difference between the first and second moving time falls within a pre-determined value, the optical disk drive is horizontal orientation.
