    • A method is described for controlling an optical disc drive apparatus (1) of a type comprising: scanning means (30) for scanning a record track of an optical disc (2) and for generating a read signal (SR); actuator means (50) for controlling the positioning of at least one read/write element (34) of said scanning means (30) with respect to the disc (2); a control circuit (90) for receiving said read signal (SR) and generating at least one actuator control signal (SCR) on the basis of at least one signal component of said read signal (SR), the control circuit (90) having at least one variable control parameter. The method comprises the steps of: deriving from said read signal (SR) at least two signals (REn; MIRn) of mutually different type; and varying the setting of said at least one variable control parameter as a function of said at least two signals. An other method is described for discriminating two kinds of disturbances originated by a) disc defects, b) schocks.
    • 描述了一种用于控制一种类型的光盘驱动装置(1)的方法,包括:扫描装置(30),用于扫描光盘的记录轨道并产生读取信号(SR); 用于控制所述扫描装置(30)相对于所述盘(2)的至少一个读/写元件(34)的定位的致动器装置(50)。 控制电路(90),用于接收所述读取信号(SR)并且基于所述读取信号(SR)的至少一个信号分量产生至少一个致动器控制信号(SCR),所述控制电路(90)具有 至少一个变量控制参数。 该方法包括以下步骤:从所述读信号(SR)导出至少两个相互不同类型的信号(REn; MIRn); 以及根据所述至少两个信号改变所述至少一个可变控制参数的设置。 描述了一种用于区分由a)盘缺陷,b)sc ances发生的两种扰动的方法。

    • The invention relates to a guiding system (10, 10') for guiding an object (3), for instance an optical read/write-unit (3) of an optical disc player, along a motor driven spindle (5). The guiding system (10, 10') comprises engaging means (12) for engaging the spindle (5) and biasing means (15) for having the engaging means (12) engage the spindle (5) with a certain spindle force (F spindle )- To improve, i.e. minimize loading of the spindle, the engaging means (12) and biasing means (15) are arranged in such way, that the spindle forces (F spindle ) exerted on the spindle (5) cancel each other out, so that their total sum, and preferably also the sum of the moments on said spindle (5) approaches zero. The invention furthermore relates to a module (1) for an optical disc player, provided with an optical read/write-unit (3), a drive system and a guiding system (10, 10') according to the invention.
    • 本发明涉及一种用于沿着电机驱动主轴(5)引导光盘播放器的光学读/写单元(3)的物体(3)的引导系统(10,10')。 引导系统(10,10')包括用于接合主轴(5)和接合装置(15)的接合装置(12),用于使啮合装置(12)以一定的心轴力(F < SUB>主轴) - 为了改善,即最小化主轴的载荷,接合装置(12)和偏置装置(15)以这种方式布置,使得主轴力(F < (5))相互抵消,使得它们的总和,优选地也是所述心轴(5)上的力矩之和接近零。 本发明还涉及一种具有根据本发明的光学读/写单元(3),驱动系统和引导系统(10,10')的用于光盘播放器的模块(1)。
