摘要： PURPOSE: An apparatus for controlling a tilt of a disc player and a method of compensating the apparatus are provided to control the tilt more accurately. CONSTITUTION: An apparatus for controlling a tilt of a disc player includes a pick-up and a tilt sensor(100). The pick-up reciprocates between the inner part and outer part of a disc(10) mounted on a spindle motor(105). The tilt sensor has a light-emitting element set at the center thereof and a light-receiving elements located at both sides of the light-emitting element. When a virtual line passing through the center of the light-emitting element and the center of the light-receiving element is a tilt sensor center line(03), a virtual line passing through the center of the disc and the center of a light irradiation part(2) of the pick-up is a light irradiation part center line(01), a virtual line passing through the center of the disc and the center of the light-emitting element is a light-emitting element center line(02), and a virtual line parallel with the light irradiation part center line is a parallel tilt sensor center line(04), the tilt sensor is installed in the apparatus such that the tilt sensor center line is located between the parallel tilt sensor center line and the light-emitting element center line.
摘要翻译：目的：提供一种用于控制盘播放机倾斜的装置和补偿装置的方法，以更精确地控制倾斜。构成：用于控制盘播放机倾斜的装置包括拾取器和倾斜传感器（100）。拾取器在安装在主轴电机（105）上的盘（10）的内部部分和外部部分之间往复运动。倾斜传感器具有设置在其中心处的发光元件和位于发光元件两侧的光接收元件。当通过发光元件的中心的虚拟线和受光元件的中心是倾斜传感器中心线（03）时，穿过盘的中心的虚拟线和光照射的中心拾取部分（2）是光照射部分中心线（01），穿过盘中心的虚拟线和发光元件的中心是发光元件中心线（02），并且与光照射部中心线平行的虚拟线是平行倾斜传感器中心线（04），倾斜传感器安装在该装置中，使得倾斜传感器中心线位于平行倾斜传感器中心线和发光元件中心线。

摘要： PURPOSE: A method of recording and reproducing an optical record carrier is provided to detect tilt amount of a disc in a free-running state and to detect tilt direction thereof from a focus error signal, thereby compensating for the tilt. CONSTITUTION: The method of recording and reproducing an optical record carrier(101), wherein a tracking error signal and a focus error signal is detected using an electrical signal of an optical pick-up(102) which irradiates a laser beam onto a specified position on the record carrier and picks up a reflected beam therefrom to perform a tracking servo and a focus servo, comprises the steps of: detecting magnitude and direction of a tilt while rotating the optical record carrier upon mounting it to adjust the tilt, followed by performing a process of storing the adjusted values as a reference value for every specified position on the record carrier; and applying the stored reference value to an appropriate position on the record carrier upon operation thereof, to effecting a tilt compensation.
摘要翻译：目的：提供记录和再现光学记录载体的方法以检测自由运行状态下的盘的倾斜量并从聚焦误差信号检测其倾斜方向，从而补偿倾斜。构成：记录和再现光学记录载体（101）的方法，其中使用将激光束照射到指定位置的光学拾取器（102）的电信号来检测跟踪误差信号和聚焦误差信号，在记录载体上并从其上拾取反射光束以执行跟踪伺服和聚焦伺服，包括以下步骤：在安装光学记录载体的同时旋转光学记录载体以调整倾斜度时，检测倾斜的大小和方向，然后执行将调整后的值作为基准值存储在记录载体上的每个指定位置的处理; 以及在操作时将所存储的参考值应用于记录载体上的适当位置，以进行倾斜补偿。
