    • A track jump method for an optical recording/reproducing medium is provided. In the track jump method, once a track jump command is input, a track jump operation is held until a falling edge of a header mask signal is detected. The track jump starts at the falling edge of the header mask signal and ends before a rising edge of the header mask signal so that a TZC signal is not influenced by a header during the track jump. Therefore, the track jump can be exactly and stably performed. In particular, when the track jump command is input, a PLL of a wobble signal is inhibited, and a PLL-wobble signal is held to a previous value obtained before the track jump is performed, during the track jump, or a header mask signal is generated using a read channel signal which is not influenced by a wobble period, until a wobble signal becomes stable after a trackjump. During a normal servo, a header mask signal is generated using a PLL-wobble signal to mask a header area. Therefore, a header area coming first after the trackjump is completed can be stably masked, thereby preventing a system from being unstable due to a header during the track jump.
    • 提供了一种用于光学记录/再现介质的轨道跳跃方法。 在轨道跳跃方法中,一旦轨道跳转命令被输入,轨道跳转操作被保持,直到检测到标题屏蔽信号的下降沿。 磁道跳转在标题屏蔽信号的下降沿开始,并且在标题屏蔽信号的上升沿之前结束,使得在轨道跳跃期间TZC信号不受标题的影响。 因此,可以准确稳定地进行轨道跳跃。 特别地,当输入轨道跳转命令时,禁止摆动信号的PLL,并且将PLL摆动信号保持为在轨道跳跃期间执行轨道跳跃之前获得的先前值,或者标题屏蔽信号 使用不受摆动周期影响的读通道信号产生,直到摆动信号在轨迹之后变得稳定。 在正常伺服期间,使用PLL摆动信号产生标题屏蔽信号以屏蔽报头区域。 因此,可以稳定地掩盖在轨迹开始完成之后首先出现的首标区域,从而防止系统在轨道跳跃期间由于头部而不稳定。

    • A method of recording and reproducing an optical recording medium which detects a defocus and a tilt of the optical recording medium and compensates the detected defocus and tilt in a high-density optical recording medium. In a free running state in which only a focus servo is turned on, the amount of defocus offset that corresponds to a maximum level of a tracking error signal is detected in a plurality of positions on inner and outer peripheries of a disc, and a tilt-zero in the respective position is detected and stored, so that a tilt servo and a focus servo are performed with the value stored in the corresponding position during an actual recording/reproduction. The method can prevent the deterioration of quality of data due the defocus during recording/reproduction, enabling real time recording by quickly stabilizing the focus servo, and stable operation of the system. Also, the method can follow corresponding tracks with a rapid stabilization of servo during a search or seek, and detect and compensate for the tilt stably and accurately in the high-density optical disc. The method can also prevent the deterioration of quality of data and a detrack due to the tilt during recording/reproduction, and thus achieve stable operation of the system.
