Abstract
PURPOSE:To provide an optical card which can easily recorded by projection of a low-power light beam by using a film which forms bubbles as a recording film and using a material selected from materials, the hardness of which is in a 30-60 durometer hardness range, as an org. adhesive layer. CONSTITUTION:This card is made into 4-layered structure consisting in laminating the recording film 2, the org. adhesive layer 3 and a protective org. sheet 4 on a transparent org. substrate 1. Deformed build-up parts (bubbles) 5 are formed on the recording film 2 when the light beam for recording pulse- modulated by the information to be recorded is projected to the card from the transparent org. substrate 1 side. The recording film 2 is the thin film consisting of a mixture composed of thermally and chemically stable refractory particles, fine metallic particles and org. matter. The transparent org. substrate 3 has the hardness in the 30-60 durometer hardness range. The light beam of relatively low power for recording necessary for forming the deformed build-up parts 5 suffices and the easy recording is executed by a semiconductor laser.
