Optical disc driver tilting regulator

Abstract

The optical disc driver inclination regulator includes laser head base to support the laser head moving on the guide shaft inside the optical disc driver; motor seat on the laser head base and with motor to rotate the main shaft for optical disc; and inclination regulating screws including fixed screws, radial inclination regulating screws and tangent inclination regulating screws to ensure the vertical irradiation of the laser beam to the signal record surface of the optical disc. The present invention with the special design has high inclination regulating precision and increased regulating range.

Description

(1) Technical field [0001] The present invention relates to an optical disc drive, in particular to an optical disc drive tilt adjustment device which can ensure that the light irradiated by the laser head is irradiated vertically or reflected on the surface of the optical disc. (2) Background technology [0002] In the optical disc drive, when recording signals on the signal recording surface of the optical disc or playing the recorded signal, the laser beam irradiated from the laser head must be irradiated vertically to the signal recording surface of the optical disc. In order to achieve this purpose, the laser head and the signal recording surface of the disc should be parallel to each other, and this position adjustment is called tilt adjustment. [0003] figure 1 and figure 2 What is shown is the structure diagram of the prior art in which the tilt adjustment is performed through the installation height adjustment of the spindle motor. As shown in the figure, the l...
