摘要： A boundary crossing detector in a tracking and focus servo system of an optical disk drive is presented. A tracking error signal can be monitored as an optical pick-up unit of the optical disk drive is allowed to move across an optical media in the optical disk drive. If a peak-to-peak value of the tracking error signal changes by a threshold value, than the boundary crossing can be indicated.

摘要： A write abort algorithm of a tracking and focus servo system that can abort a write operation on an optical disk drive is presented. The write abort algorithm monitors at least one of a tracking error signal or a focus error signal and indicates a write abort status when the tracking error signal or the focus error signal indicates a threshold value. In some embodiments, the write abort algorithms suspends indication of the write abort status in the presence of a defect, suspension of the write abort status occurs more than a predetermined number of times.

摘要： A close tracking algorithm for a tracking servo system is disclosed. The track crossing rate of an optical pick-up unit positioned over an optical media is determined. When the track crossing rate is below a threshold value, then a tracking servo algorithm is enabled. The tracking servo algorithm provides control signals to control an actuator arm that controls the position of the optical pick-up unit over the tracks of the optical media. In some embodiments, the track crossing rate can be determined by monitoring the zero crossings of a tracking error signal derived from optical signals measured in the optical pick-up unit.

摘要： A servo system with a multi-track seek algorithm with an acceleration clamp is presented. The multi-track seek algorithm detects zero crossings in a tracking error signal, counts the number of zero crossings to form a count, and calculates a reference velocity from the count. The algorithm also determines a time period between successive zero crossings, calculates a velocity from the time period, calculates a difference signal between the reference velocity and the velocity, and adjusts the control signal so that the velocity follows the reference velocity. The reference velocity can follow a velocity profile with acceleration portions, coasting portions, and deceleration portions which move an optical pick-up unit from a starting position to a target position. The acceleration of an optical pick-up unit is clamped during the multi-track seek operation.

摘要： A defect detector in an optical disk drive is presented. The defect detector indicates a defect by monitoring a sum signal. The sum signal is calculated from optical signals from detectors in an optical pick-up unit of the optical disk drive. A defect can be indicated when a filtered sum signal, the filtered sum signal being the sum signal filtered with a high pass filter, is above a threshold value. In some embodiments, the defect detector can recognize changes in laser power or transitions between media types and not indicate defects during those occurrences.

摘要： A servo system with a multi-track seek algorithm with an track zero crossing period integrity test is presented. Zero crossing periods for subsequent cycles can be determined from a tracking error signal. If the zero crossing period for a first cycle differs substantially from the zero crossing period for a second cycle, then an error can be indicated. In some embodiments, the first cycle and the second cycle are subsequent cycles. In some embodiments, the zero crossing period in the second cycle can be between half and twice the zero crossing period in the first cycle. In some embodiments, other ranges are utilized. For example, in some embodiments the zero crossing period in the second cycle can be between one quarter and four times the zero crossing period in the first cycle.

摘要： A servo system with a multi-track seek algorithm with a zero crossing detector is presented. The zero crossing detector indicates when the tracking error signal crosses zero. In some embodiments, a delay is executed between adjacent detections of zero crossings in the tracking error signal, for example half a cycle. In some embodiments, a zero crossing is detected when the tracking error signal passes through a range around zero, the range having a positive value above zero and a negative value below zero.
