Problems solved by technology

[0010] However, the problem with the regulator 23 that provides the rotational driving force for the optical disc under the above-mentioned prior art conditions is that it only supports the tracking operation, and cannot normally compensate the Z-axis direction when the position changes due to the bending of the optical disc 10 or the influence of the surrounding environment. , that is, the focal point in the direction of the optical axis

Abstract

This invention is a ROM driver with one end of the rocker rotate fixed to the rotating shaft, and the other end fixed the module of read / write model. The driver includes the following two parts: a focus serve adjuster fixed to the rotating end of the rocker; a tracing serve adjuster fixed to the other end of the rocker to supply driving power for crank motion of the rocker. With the focus serve fixed on the rotating shaft to adjust the focus point up and down, it is capable of accurately making up position change of the disk recording area at rotation.

Description

technical field [0001] The present invention relates to the technology of optical disc drive. Background technique [0002] 1 is a plan view of a conventional optical disc drive, and FIG. 2 is a schematic sectional view of a state in which a guide block of the conventional optical disc drive slides and drives the outer end of an optical disc. FIG. 2 is a schematic diagram of a device using a refractive solid immersion lens as the small lens 34 . [0003] As shown in the figure, the existing optical disc drive includes the following components: a rotatable rocker arm 21 arranged on the base of the optical disc drive (base); The end of the arm 21 can utilize hydrodynamic air pressure to float on the guide block 25 used to scan the track of the optical disc; it is arranged on the guide block 25 to form a light spot on the above-mentioned optical disc 10 for recording / reading optical information The optical magnetic head 30. [0004] The above-mentioned optical disk 10 includ...
