Abstract

There is disclosed a random-access light-emitting dot matrix (21) used for data writing process. The number and disposition of dots in the matrix is the same as the number and disposition of pits on one page of one information layer of the fluorescent multi-layer optical card. Written information can be retrieved page by page.
