摘要： A detector is scanned across an optical storage medium having groove tracks and land tracks, each track having a wobble structure, to detect light reflected from the optical storage medium. A wobble signal and a tracking error signal are generated based on an output of the detector, and the wobble signal is sampled according to the tracking error signal. A determination about whether the detector is at the groove track or the land track is made based on the tracking error signal and a comparison of sampled values of the wobble signal.

摘要： A light beam is scanned on a track of a recording medium, the track having a first track region and a second track region, each track region having a physical property that has recurring deviations. A wobble signal is derived from the light beam, the wobble signal having information associated with the recurring deviations. Whether the light beam is at the first track region or the second track region is determined based on a frequency, a period, or a pulse width of the wobble signal.

摘要： This invention provides a laser power control system to control the power of the emitted laser from an optical pick-up head. The system comprises a temperature sensor and a calculating unit. The temperature sensor is used to detect the temperature of the optical pick-up head and to generate a temperature signal accordingly. The calculating unit, storing a control relation of the optical pick-up head, is used to receive the temperature signal. According to the control relation, the calculating unit calculates and outputs a power control signal under the temperature signal and the setting power. The power control signal, converted from digital into analog by a digital to analog converter, is transmitted to the optical pick-up head, so as to control the optical pick-up head to emit the laser according to the setting power.

摘要： An optical recording method and apparatus with different recording rates are provided for effectively increasing the average recording rate. The optical recording method includes the steps of: controlling a recording rate with a constant linear velocity (CLV) control mode; recording data; judging whether the recording rate has to be increased according to a rotating speed of a spindle motor or a recording position; and performing a process for changing the rotating speed if the recording rate is increased, and continuing recording data at the same recording rate if the recording rate is not increased. The step for changing the rotating speed includes the steps of: pausing recording data; registering a paused zone of a disc; determining a new rotating speed of the spindle motor, and driving the spindle motor at the new rotating speed; and linking recording zones to continue recording data at a new recording rate from the paused zone, when the rotating speed of the spindle motor is stable. Consequently, the invention can optimize the overall average recording rate by effectively utilizing the maximum rotating speed of the spindle motor in conjunction with the CD's maximum recording rate.
