Optical storage read-write equipment and its application in economy domain computerization

Abstract

The present invention provides a read-write device of laser scanning optical memory, including: an optical read-write head, a laser scanner, an optical memory, a convex is mounted between the laser scanner and the optical memory, reading-writing data on the surface of the static optical memory, the optical memory has tracks corresponding to the scanning tracks of the laser scanning type optical memory read-write device. The optical memory is a product combined with the solid product, such as combining on all kinds of files and anti-fake labels. The surface has all kinds of files capable of writing in the optical memory for one time, including: bil, invoice, paperwork and identity card. The laser scanning optical memory read-write device and invoice and anti-fake lable which surface has writing optical memory for one time, can prevent producing and selling fake or inferior quality commodity, overdue product, write false value invoice and manipulation of accounts to process tax evasion. The device establishes an information system for limiting the under ground economic development by integrated rights of each subject of administration.

Description

Technical field: [0001] The present invention relates to an optical memory reading and writing device, and a product combining the optical memory corresponding to the device with a solid object, especially on various documents and anti-counterfeiting labels, as well as using various documents with optical memory on the surface And anti-counterfeiting labels in the economic field to establish the information system method. Background technique: [0002] In recent years, the proliferation of the underground economy has resulted in a large loss of tax revenue. Some economists estimate that based on the scale of my country's GDP of 10 trillion yuan in 2002, the total amount of my country's underground economy should be between 1.5 trillion yuan and 2 trillion yuan. According to the calculations of relevant departments, the loss of my country's tax revenue in 2000 should be more than 300 billion yuan, while the overall loss of my country's tax revenue in 2001 was between 320 bil...

Problems solved by technology

The disadvantages of manual input into the computer through the keyboard are: low speed, low efficiency, high error rate, and the possibility of artificial tampering, and the authenticity of the data cannot be guaranteed

Since the existing original vouchers are only paper-based written materials, the original vouchers are manually input through the keyboard or through a scanner, and the disadvantages of manual input cannot be avoided.

The disadvantages of floppy disk transfer and network transmission are: the data is easily tampered with, and the authenticity of the data cannot be guaranteed

So far, there is no way to prevent manufacturers from manufacturing and selling fake products, and merchants from buying and selling fake products.
