摘要： PURPOSE: Recording medium, a data recording method, and an apparatus thereof including a plurality of layers are provided to perform efficient focus servo in a desired layer after reading previously recorded information in a corresponding layer. CONSTITUTION: One or more first separation combining units(30,31) pass through a reference beam or a recording beam along a polarization direction. The first separation combining units reflect the reference beam. A second separation combining unit(40) passes through the reference beam or the recording beam. The second separation combining unit reflects the reference beam or the recording beam. A reference beam receiving unit(70) receives the reference beam reflected from recording medium. A recording beam receiving unit receives the recording beam reflected from the recording medium. [Reference numerals] (10) Reference beam light source; (20) Recording beam light source; (50) Lens unit; (70) Reference beam receiving unit; (80) Recording beam receiving unit; (AA) Layer 0; (BB) Layer 1
摘要翻译：目的：提供记录介质，数据记录方法及其包括多层的装置，以便在读取相应层中的先前记录的信息之后，在期望的层中执行高效的聚焦伺服。构成：一个或多个第一分离组合单元（30,31）沿偏振方向穿过参考光束或记录光束。第一分离组合单元反映参考光束。第二分离组合单元（40）穿过参考光束或记录光束。第二分离组合单元反映参考光束或记录光束。参考光束接收单元（70）接收从记录介质反射的参考光束。记录光束接收单元接收从记录介质反射的记录光束。（附图标记）（10）参考光束光源; （20）记录光源; （50）镜头单元; （70）参考光束接收单元; （80）记录光束接收单元; （AA）层0; （BB）层1

摘要： PURPOSE: A tilt controlling method and an apparatus thereof are provided to improve the reliability of a recording/playing device by estimating the absolute amount of tilt errors for controlling an active tilt control. CONSTITUTION: A tilt controlling apparatus includes an optical pick-up(100), a signal processing unit(110), a controlling unit(120), a gap servo driving unit(130), a tilt servo driving unit(150), a main controlling unit(160), an interface(170), and a spindle motor. The signal processing unit generates a gap error signal or a tilt error signal. The controlling unit determines whether tilt between a lens unit and a recording media is controlled. The controlling unit transmits a driving signal to a motor driving unit.
摘要翻译：目的：提供倾斜控制方法及其装置，通过估计用于控制主动倾斜控制的倾斜误差的绝对量来提高记录/播放装置的可靠性。构成：倾斜控制装置包括光学拾取器（100），信号处理单元（110），控制单元（120），间隙伺服驱动单元（130），倾斜伺服驱动单元（150），主控单元（160），接口（170）和主轴电机。信号处理单元产生间隙误差信号或倾斜误差信号。控制单元确定是否控制透镜单元和记录介质之间的倾斜。控制单元将驱动信号发送到电动机驱动单元。
