Problems solved by technology

[0004] When the disk loading device is placed in the horizontal direction of the movement, the shock-absorbing assembly can make the optical pickup drive part in a suspended state, and elastically support the optical pickup drive part to play a shock-absorbing role; but this shockproof connection assembly The structure is relatively complicated, and the cost of the grease shock absorber is relatively high, and if the movement is placed upright or placed at a large inclination angle relative to the horizontal direction, the driving part of the optical pickup will deviate from the original position due to the effect of gravity. position in the base, so that the shock-absorbing components of the movement will lose the shock-absorbing function, so that the disk loading device cannot work normally; Misalignment of the optical pickup drive unit from its original position in the base also has the potential to prevent the disc loader from functioning properly
[0005] The structure of the disk loading device is relatively complex, and its appearance size is relatively large, and its clamping of the optical disk is realized by moving up and down the drive part of the optical pickup, which will have a certain impact on the service life of the disk loading device
