Embodiment Construction

[0013] The present invention is a high-density master recorder with a new structure. The new high-density master recorder shown in Figure 1 is mainly composed of a high-precision table fixed on the air-floating turntable, which is used for Z-direction gap adjustment and focus adjustment of the optical system. The Z-direction upright table consists of an optical writing head, an air-floating spindle and a master disk. Its control system 1 and electric control interface 2 are fixed under the air-floating turntable 3, and the linear grating reading head 4 is fixed on the air-floating turntable 3. The linear grating 5 and the precision table 7 are connected and fixed near the linear grating reading head 4, and the radial motor 6 is fixed on the right half of the table surface of the air bearing turntable 3 after being connected with the precision table 7 with high-precision screw 17 and radial movement; The Z-direction upright table 8 fixed on the precision table 7 is connected wit...

Abstract

A high-compactness mother disc CD-RW device is precisely controlled by the control system fixed under the rotating air-floating table. It has the precise table radially moving on high-precision optical raster, vertical table, optical writing head and the drive of air-floating mainshaft of mother disc. Its advantages are compact structure, closed-loop control, and high locating precision and reliability.

Description

technical field [0001] The invention belongs to the technical field of optical disc recording, and in particular relates to a novel high-density master disc recording machine for reading and storing high-density optical disc signals. Background technique [0002] High-density master recording system is an emerging scientific research topic, involving science and technology in different fields such as electronics, machinery, materials, optics, manufacturing, measurement, physics, and chemistry. Due to the important role of high-density master recording in optical storage technology, Highly regarded. At present, a lot of research work has been done in this area at home and abroad, such as CD / VCD, DVD, etc., but their storage density (or capacity) is far from meeting the requirements of information storage carriers for the rapid development of the information society. With the popularization and development of the network and the wide spread of multimedia technology, the tradi...
