Description of the invention (f) This invention also provides another automatic adjustment device for the optical axis, which can respond to the reflected voltage signal, The selective adjustment device is used to automatically drive the plurality of adjustment devices to further adjust the optical axis of the optical storage reading device accurately. ^ Only ~ prepare n As described in the above, the light error signal is not a “jail value”. It is expected that the degree of change in the value of the interference mosquito green difference signal increases when «, which causes trouble in judgment. For example, the quality of the optical disc itself, whether it is fouled, or whether there is interference from external noise, etc., will cause a considerable amplitude of the optical error signal. Another aspect of the present invention is the optical axis automatic adjustment device, which discards the light error money and uses the reflected light signal as a reference for judgment. After the data read-write device transmits the light incident signal to the optical storage medium, the light incident signal is converted into the light reflection signal by the reflection of the read memory. The data writing device reads the radio money and converts the light reflection signal into the reflection voltage signal. The waveform of the reflected voltage signal is a waveform similar to a sine wave. When the light incident signal or the optical axis is perpendicular to the optical storage medium, the intensity of the reflected voltage signal is the largest, that is, the peak-to-peak voltage value of the reflected voltage signal. For the biggest. Conversely, when the optical axis is not perpendicular to the optical storage medium, the reflected voltage signal will weaken, that is, the peak-to-peak voltage value of the reflected voltage signal will also weaken, and it will rapidly decay as the degree of deviation increases. Mainly because the reading area of the data reading and writing device is fixed, when the optical axis is not perpendicular to the optical storage medium, the light reflection signal converted by the reflection of the optical storage medium into the light reflection signal is due to angular deviation It is only partially read by the data read-write device, because the data read-write device can only convert the read light reflection signal into the reflected voltage signal, so the reflected voltage signal will gradually weaken. Please refer to the seventh figure. The seventh figure is a comparison chart of the relationship between the reflected voltage signal and the traditional optical error signal at different incident angles. In the seventh picture --- jASUSTEK-199917T W _ s (paper size " house standard (CNS) specifications (21 () > < 297 public magic ^ -1 clothes order -------- ^ ball f please Read the notes on the back before filling this page.)

Description of the invention (price): The second-line silk is poor, and the A-line Wei mercerization error signal is at a fixed angle The degree of unstable changes caused by external interference. The B wire shows the repeated electric signal, and the line width of the B line also indicates that the reflected electric dust signal is under the radiant radiance of the mouth. The degree of change is # Comparison of the line width of line B and line A. It can be seen that the present invention uses the reflected voltage signal to adjust the optical signal or optical axis direction, which is not easy to be called by the outside world, such as' the optical disc product is bad, the optical disc The film is contaminated and other factors, and there is a large change. In other words, the reflected voltage signal is at a fixed incident angle, and 'f mild phase # is small. In addition, in the seventh figure, when the input degree changes slightly

Therefore, as another aspect of the present invention, the optical axis automatic adjustment device uses the reflected signal as a trigger, and the reflected voltage signal has a more sensitive change to the incident angle, so the incident angle can be accurately adjusted to the optimal state. Therefore, according to another aspect of the present invention, the optical axis automatic adjustment device can respond to the number of reflected electric cranes.
