改善滚珠自动平衡系统滚珠平衡位置的方法

A method for improving the balance position of the balls in an automatic ball balancing system used for optical disc drive, which has a rotor mechanism consisting of mainshaft motor, a rotor with ring slot, and balls in said ring slot, features that said ring slot has a surface with low friction coefficient and the rotation speed at which rotor is stable and the system phase angle of ball when rotor is stable are changed for higher balancing effect.

光驱光读写头工作取角的方法

The present invention is a method for determining an operating angle of an optical reading and writing head of an optical driver, which is used in a jitter checking device comprising a fixture for simulating and adjusting the tilt angle of the optical reading and writing head and a jittering instrument for measuring the jitter value of the optical reading and writing head at the different tilt angles. In this method, the measured points are reduced to five by means of the empirical formula, and as the basis for adjusting the operating tilt angle of the optical reading and writing head, the minimum jitter value and the optimum tilt angle of the optical reading and writing head can be calculated rapidly without the necessity of performing the zero adjustment of the radial and tangential tilt angles respectively.

光学校准机自动测量方法

The invention relates to an automatic measurement method for the optical adjusting machine characterized by that, after the picture of the measured object is taken by the charge coupling assembly module, the program will automatically determine whether there is any reflection bright point on the photographed picture by the charge coupling assembly module and perform automatic measurement, thus avoiding the misoperation and negligence of the user.
