System-grade chip for second-level addressing high-density mother disk recording machine

Abstract

The system-level chip of the secondary addressing high-density master disk recorder belongs to the field of ultra-high-density optical storage technology and ultra-large-scale integrated circuits. In order to solve the problem of precise addressing and positioning and stable and high-speed focusing and recording of high-density master disc recorder, the present invention discloses a system-level chip of secondary addressing high-density master disc recorder, including master control of master disc recorder device, system bus, addressing and positioning digital servo, error signal detector and optical system controller; error signal detector includes addressing and positioning error signal detector and focus positioning error signal detector; optical system controller includes near-field SIL The focusing controller and the laser controller; the addressing and positioning digital servo, the error signal detector and the optical system controller are respectively connected with the main controller of the master disc recorder through the system bus. The invention has the advantages of high integration, low power consumption, strong anti-interference ability, small error and fast control processing speed.

Description

technical field [0001] The invention relates to a new-generation ultra-high-speed and ultra-high-density optical storage system using VLSI technology, and belongs to the fields of ultra-high-density optical storage technology and VLSI technology. Background technique [0002] High-density data storage technology has always been an indispensable key research field in the development of information technology and computer technology. It is estimated that in 2005, the external storage capacity of computers should be at least 100GB, and the data transmission rate should be at least 40Mbps. The goals are far away. It is necessary to adopt new technologies and new materials, research and develop a new generation of high-density, high-speed optical storage technology and systems. [0003] The key to high-density optical storage technology is to increase the density of optical discs, and the decisive factor for increasing the density of optical discs is the burning of high-density ...

AI Technical Summary

Problems solved by technology

This board-type circuit system, although the speed of the integrated circuit IC unit can be very high, and the power consumption can be small, but due to the connection delay between the integrated circuit IC units in the circuit, the reliability of the circuit board and the weight of the circuit board, etc. Restrictions, the performance of the whole system is greatly restricted

It cannot meet the requirements of fast response speed, strong anti-interference ability, high adaptive sensitivity and reliable operation stability of addressing and positioning in ultra-high-density mastering.
