Description

Electronic device with head adjustment

technical field

The invention relates to an electronic device and its optical reading head adjustment structure, in particular to an electronic device with an optical reading head inclination adjustment structure and an electronic device with a read-write head adjustment.

Background technique

In recent years, using optical discs to record audio, video and personal file data has become a data storage method commonly used in people's lives. Due to the large amount of recording space and the characteristics of being easy to carry and save, people can use the CD to exchange information quickly and get a lot of fun from it. Among them, the optical disc drive, as an optical disc reading device, has become an indispensable member of today's computer peripheral equipment.

Generally speaking, when an optical disc drive reads data from an optical disc, the jitter (Jitter) of the radio frequency (RF) signal returned by the optical read/write head is directly proportional to the read error rate (Error Rate). When the amount of jitter is large, the error rate will also increase, and even lead to read failure in severe cases. If the optical quality of the laser light reflected back to the optical read-write head by the optical disc is better, the jitter of the radio frequency signal can also be suppressed accordingly. Therefore, it is necessary to make the optical axis of the optical read-write head (the laser light path projected by reading and writing) perpendicular to the surface of the optical disc as much as possible, so that the scattering and refraction loss of the laser light can be reduced during the reflection process.

Please refer to FIG. 1 , which is a schematic diagram of a conventional optical pickup head tilt adjustment mechanism. In order to make the optical axis of the optical read-write head perpendicular to the surface of the optical disc as much as possible, the existing known optical disc drives, especially for DVD disc drives that are more sensitive to optical axis errors, have an optical pick-up head inclination adjustment mechanism 10, which includes a spindle motor (spindle motor) 11, a disc loader (disk loader) 12 arranged on the upper edge of the spindle motor 11 and an optical read-write head 13, which is mounted on a sliding base 14 , can be driven by a transmission motor (sled motor) to move back and forth along the guide rail 15, so that the optical read-write head 13 can move horizontally along the disc surface of the optical disc.

In order to keep the surface of the optical disc perpendicular to the laser light emitted by the optical read-write head 13, the operator needs to accurately adjust the inclination angle and height of the guide rail 15 so that the laser beam of the optical read-write head 13 mounted on the guide rail 15 The light is parallel to the plane normal vector of the upper surface of the disc holder 12 . In this way, when the optical disc is placed on the disc carrier 12, the laser light path of the optical read-write head 13 can accurately read and write the data on the disc.

However, the existing known optical head inclination adjustment mechanism 10 is to rotate the screw 16 connected to the end of the guide rail 15, and use the locking and loosening of the screw 16 to change the height of the fulcrum of the guide rail 15, and use the elastic piece 17 to suppress guide rail to adjust the inclination angle and height of guide rail 15. Therefore, the adjustment action cannot be quantified, and the reproducibility of turning the screw 16 is not good, making it difficult to control the accuracy. The operator needs to repeatedly adjust and the feedback signal also needs to be repeatedly confirmed during automatic adjustment, so a lot of time is wasted. And when the adjustment is completed, it is necessary to carry out the action of dispensing glue with the screw 16 to fix the height of the adjusted guide rail 15 .

It can be seen that the above-mentioned existing electronic device with head adjustment obviously still has inconveniences and defects in structure and use, and needs to be further improved urgently. In order to solve the problems existing in electronic devices with read/write head adjustment, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure for general products to solve The above-mentioned problem is obviously a problem that relevant industry players are eager to solve.
