Regulation system of screen display by using optical driver and its method

Abstract

The present invention discloses a regulation system of screen display used by optical drive and its method. It utilizes an electronic collimator to sense and measure the inclination and oscillation of rotating disk, and utilizes a switching box to transfer the signal into a machine equipment. The inclination of the optical head can be fetched by fetch machine and can be transferred into a computer host, and calculated and obtained, and signal signal can be transferred into the machine equipment by means of buss and utilizing OSD (On Screen Display) instruction. The machine equipment computer host to make wired or gate operation. It can utilize computer host to calculate and obtain different inclination regulations of optical head in different optical paths for fetching CD or DVD optical disk.

Description

technical field [0001] The invention relates to an adjustment system and method for an optical drive using screen display, in particular to an optimal inclination adjustment during the assembly process of the optical drive by using an OSD display method. Background technique [0002] In general optical drives (such as DVD-ROM, DVD-LATER, CD-R, CD-RW), the optical head (Pick-Up head) can be said to be the core component for reading data inside the optical drive. To fetch data from an optical disc, there are certain strict requirements on the tilt angle (tilt) between the optical axis of the optical head and the optical disc, so that the data reading process can be smoother and smoother. However, it is difficult to achieve the specified inclination angle only by controlling the precision of the parts, which is difficult in terms of product yield and cost in production and implementation. Therefore, it is necessary to design a tilt adjust mechanism (tilt adjust mechanism) and u...

AI Technical Summary

Problems solved by technology

[0006] (1) The jitter meter is susceptible to noise interference when reading RF signals, making it impossible for the jitter meter to directly determine the optimal jitter value of the optical head

[0007] (2) The jitter meter uses the deflection of the pointer to represent the measured jitter value. It is not easy to judge whether the optimal jitter value has been reached, and it needs to be tested several times to determine the optimal jitter value bottom (bottom Jitter)

[0008] (3) Since the optical path required by the optical head to read CD or DVD discs is not the same, that is to say, adjusting the plane of the rotating disk and the guide rod carrying the optical head to the same plane cannot be adjusted for individual differences in the optical head

During the operation, the operator needs to switch the screen frequently, causing the screen to flicker and causing discomfort to the operator

[0009] (4) The adjustment of inclination, yaw, and jitter cannot be performed at the same time, resulting in a longer adjustment time
