    • A tracking control apparatus is provided for controlling a displacement error between a pickup system and a track when reproducing information recording on an information-recording and reproducing medium having tracks on which information is recorded or reproduced. The tracking control apparatus includes on-track detecting means for detecting a light beam is located on the track, traveling-direction detecting means for detecting the direction of the pickup system traveling toward the track from the displacement error and the output signal supplied by the on-track detecting means and outputting a traveling-direction signal representing the traveling direction, track-slippage detecting means for detecting a track-slippage signal representing the direction of the light beam being slipped out of a target track from the traveling-direction signal supplied by the traveling-direction detecting means, and tracking control means for supplying as a control signal the displacement error when the light beam is located on the target track or as a control signal the track-slippage signal supplied by the track-slippage detecting means when the light beam is not spotted on the target track and driving the pickup system in a manner to allowing the light beam to follow the tracks.

    • There are provided an optical disk device and tilt correction processing method for performing recording/reproduction by rapidly acquiring an optimal tilt correction value for an optical disk having a plurality of recording/reproducing layers. In an optical disk device capable of recording or reproducing information by irradiating a laser beam to each of a plurality of recording/reproducing layers of an optical disk, the tilt value is stepwise set within a predetermined range at a predetermined radius position of the recording/reproducing layer located at the farthest distance from the laser beam irradiation side so that an optimal tilt correction value can be obtained from the quadratic function by the method of least squares of the jitter or the like obtained from the disk. By applying the optimal tilt value obtained to the other recording/reproducing layer, it is possible to start recording or reproduction in a short time.
    • 提供了一种用于通过快速获取具有多个记录/再现层的光盘的最佳倾斜校正值来执行记录/再现的光盘装置和倾斜校正处理方法。 在能够通过向光盘的多个记录/再现层中的每一个照射激光来记录或再现信息的光盘装置中,倾斜值被逐步设定在记录/再现层的预定半径位置的预定范围内, 再现层位于距离激光束照射侧最远的距离处,从而可以通过从盘获得的抖动等的最小平方的二次函数获得最佳倾斜校正值。 通过将获得的最佳倾斜值应用于其他记录/再现层,可以在短时间内开始记录或再现。
