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： 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： In a tracking control apparatus, a tracking error signal having a level of a positional shift of a beam of light projected through an optical head onto a recording medium is detected based on a reflected light from the recording medium, and the optical head is controlled so that a beam of light scans on the track to be recorded or reproduced based on the tracking error signal. Offset values of the tracking error signal on adjustment tracks which are predetermined among a plurality of tracks of the recording medium are detected, and then coefficients of a predetermined approximate equation approximately representing an offset value characteristic on the track based on the detected offset values are calculated. Further, an offset value corresponding to the track to be recorded or reproduced is calculated based on the first approximate equation with the calculated coefficients, and an offset value of the tracking error signal is corrected based on the calculated offset value.

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.
