Traditional storage media can be roughly divided into two categories, namely magnetic recording media and optical information storage media. Currently, the market is dominated by optical information storage media, which include read-only optical discs (cd_r〇m), write-once optical discs (CD-R), re-readable optical discs (CD_RW), and read-only type. Digital audio and video discs (DVD_R0M), writable _ sub-digital audio and video discs (DVD-R), re-writeable digital audio and video discs (dvd_rw, dvd+rw), and dynamic random memory digital audio and video discs (DVD_RAM), etc. .

The elastic member 323 and the end of the biasing arm 324 are both fixed to the first correcting member 321, and the other end of the biasing arm is fixed to the base. In the correction, the pulling or rolling of the force applying arm is like applying the force f to the first correcting element 321 'after the correction is completed, then the applying force 24 is relaxed, and the elastic element 323 is applied - the restoring force F' is in the first Correction element 321. In this way, the first correction element 321 can be moved on, for example, the direction axis.

Further, the enlarged portion 351 has a slope 352, and the first hole 411 and the second hole 421' are first caught in the enlarged portion 351 of the pillar 35. In this way, the first substrate 41 and the second substrate 42 ′ can be initially positioned by the enlarged portion 351 to assist the first substrate 41 and the second substrate 42 ′ in the first correcting component 32 and the second calibration. On element 33. When the second substrate 42 is placed on the enlarged portion of the hollow pillar 35, the hollow pillar 35 can be moved downward, so that the first correcting member 32 and the second correcting member 33 slide against the inclined surface 351, and the elastic pillar 35 is The second substrate 42 is dropped onto the first substrate 41, and the first correcting element 32 and the second correcting element 33 pass through the first hole 411 and the second hole 421 for subsequent processing. Misalignment correction. Next, referring to FIG. 7 and FIG. 8 , the first correcting element 32 and the second correcting element 33 are respectively driven by the first power component 322 and the second power component 332 to move in the direction D1 and the other direction D2 respectively. The first substrate 41 and the second substrate 42 are brought into contact with the cushioning member 35. 12 1263214 In this embodiment, the second hole 421 of the second substrate 42 is larger than the first hole 411, so that the first; j; the parent positive element & when pushed outward, the elastic buffer S 34 can assist The second hole 421 is placed so that the second substrate 42 can also be moved by force, so that the centers of the first hole and the second hole are aligned with each other. That is to say, even if the size of the first hole 4 ιι and the second hole 42 不 is not (four) 'the misalignment correcting device of the (4) signal storage medium in the embodiment can have an elastic buffering element to make up for the holes 411, 421 The difference ' makes the centers of the holes 4 ΐ, 42 ι align with each other. In summary, the misalignment of the optical information storage medium of the present invention: the correction component and the second correction forest pass through the holes of the first substrate and the plate. The first correcting element and the second correcting element are respectively moved in opposite directions to simultaneously push the first substrate and the second substrate, and the vertical:=Γ is aligned with each other. Compared with the prior art, the optical information of the present invention=the misalignment correcting device of the present invention can be (4) the post-silus shrinkage rate is not aligned with the second substrate, or the first substrate and the sub-substrate 6 are prevented from being combined. The misplacement, so it can reduce the occurrence of eccentricity, in order to facilitate the optical reading of the track, and can make light: #财特储加. Ding Wei. The above description is intended to be illustrative, and not restrictive, and the scope of the invention is intended to be included in the scope of the appended claims.
