    摘要: The present invention discloses a system for speed error compensation. A predetermined speed signal subtracts a feedback speed signal to generate a speed error signal, and a microprocessor receives the speed error signal and outputs a calculated result. A feedback controller receives the calculated result and generates a first tracking control effort signal. A feedforward controller receives the speed error signal and generates a second tracking control effort signal according to a DC steady state error in the speed error signal. An optical head module moves at an actual speed determined by the total of the first tracking control effort signal and the second tracking control effort signal. A gain controller generates the feedback speed signal according to an actual speed signal detecting from the actual speed.

    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.

    摘要: A method of controlling a sled motor control signal (FMO) is disclosed. First, a predetermined FMO is assigned to move a sled, and a photo signal is monitored. The FMO is off after a predetermined number of waveforms have appeared in the photo signal. Then, a position of an optical pickup is finely adjusted such that the optical pickup is at a center position of a movable range after the seeking operation.

    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.
