摘要： A data-track search apparatus is provided with: a tracking error detection unit for detecting a positioning error between a light beam on a record carrier and a track; a moving unit for moving the light beam on the record carrier in a direction traversing the tracks on the record carrier; a focusing control failure detection unit for detecting a focusing control failure, and a control unit for controlling the moving unit in response to an output signal from the tracking error detection unit during the search for a desired track. The control unit regulates the moving unit so as not to accelerate but to decelerate the moving unit in the event of a focusing control failure.

摘要： In an apparatus for searching a desired track of a recording carrier by transferring and controlling the reproduction position of the pickup for reproducing the signal recorded on a recording carrier on the basis of reference transfer information, the traveling load is measured, and the value of the reference transfer information is corrected according to this measured value, so that the desired track may be searched stably. The transfer motor is driven so that the reproduction position may move at a constant velocity, and the traveling load is measured. The transfer motor is driven so that the moving speed of the reproduction position or the time for moving a specified distance may be predetermined specific value, and by this driving signal, the value corresponding to the traveling load is determined.

摘要： The temperature around the tracking actuator is detected with a temperature sensor, and the characteristics of an equivalent digital filter are changed to match the characteristics of the tracking actuator at the detected temperature. When the temperature is low, a current is applied to the focus control coil to raise the temperature of the tracking actuator, thereby essentially matching the transfer functions of the tracking actuator and the equivalent filter.

摘要： A tracking control target position adjusting track is provided on a recording carrier, where the track contains a preliminarily recorded first position-adjusting signal adjoining one side of track and a second position-adjusting signal adjoining the other side of track. While the reproduction position set on the target-position adjusting track, the tracking control apparatus adjusts the tracking-control target position based on reproduced first and second position-adjusting signals. As a result, the tracking control apparatus can precisely adjust the tracking control target position, thus providing quite satisfactory interchangeability with the corresponding apparatuses.

摘要： A velocity detection method and an apparatus therefor, in which the relative velocity between a light beam and tracks is detected on the basis of a period for which the light beam crosses the tracks, and under the condition that the light beam has passed by a predetermined position on the way to the target track, the detected relative velocity is compared with a predetermined velocity value so that when the detected relative velocity is larger than the predetermined velocity value the detected relative velocity is invalidated on the assumption that erroneous detection is generated by noise.
