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.
