Embodiment 1

[0123] Embodiment 1: The laser-scanning optical memory read-write device is composed of software and hardware, and the software includes: a laser-scanning optical memory read-write device driver and a laser scanner control program. Hardware includes: optical memory, adapter cards and laser scanners.

[0124] The laser scanner driver is a device management program in the operating system software, just like an ordinary CD driver. In microcomputer systems, this part is often solidified in the ROM of the system board. The device management program in the operating system software includes: I / O scheduler, device read / write management program, buffer management program, and device driver. Under the control of the laser scanner driver, issue operation commands to the adapter card, recycle relevant status information, accept interrupt requests and DMA requests, send and receive data information, etc. At the level of the driver program, it will involve the physical characteristics a...

Embodiment 2

[0132] Embodiment 2: Another preferred embodiment of the laser scanning optical card reading and writing device of the present invention is as follows image 3As shown, the device has an optical read-write head 1 fixed, and a collimating lens 2 and a simple double-mirror system are installed in front of the optical read-write head 1 . The simple double-mirror system has two reflecting mirrors, an x-axis reflecting mirror 31 and a y-axis reflecting mirror 32, a convex lens 33 is installed between the x-axis reflecting mirror 31 and the y-axis reflecting mirror 32, and a convex lens 33 is installed between the y-axis reflecting mirror 32 and the optical memory 5 A convex cylindrical lens 34 is installed between them. The scanning axis of the x-axis reflector 31 (i.e. the center of rotation of the mirror surface) intersects the optical axis of the convex lens 33 at point c, which is the light deflection point of the first scanner 31, and point a is also the front focus of the con...

Embodiment 3

[0133] Embodiment 3: Another preferred embodiment of the laser scanning optical card reading and writing device of the present invention is as follows Figure 4 As shown, the laser scanning type optical memory read-write device has a plurality of optical heads, and there are multiple areas or optical tracks corresponding to the number of optical heads on the optical memory. The optical structure of the laser scanner uses a relay lens system, and these optical heads can be arranged arbitrarily. Either on one plane or not on one plane. As long as the light beam emitted by each optical head hits the light deflection point of the first scanner, that is, the focus of the scanning axis and the optical axis of the lens, and the scanning range is within the first lens. An arrangement of the bald heads is: a part of the bald heads are arranged on a plane A, such as Figure 4 The arrangement position of the optical head 141, 142, 143 in. And another part of the bald head is arranged o...

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...
