Improved optical support (1) for data storage, of the type having a non- circular profile, or a circular profile with a non-standard diameter, apt to be used, through a hole (3) formed into the support, in reading and/or writi ng devices of CD or DVD disks, the housings of which are provided with at least two circular seats for disks of standard dimensions. According to the invention, the support (1) comprises a central portion, the perimeter of whi ch is inscribable into the one of said circular seats having a smaller diameter , and a peripheral portion, the perimeter of which corresponds to said non- circular profile or to said circular profile with a non-standard diameter, said peripheral portion being steadily associated to said central portion an d being less thick than the same, so that said central portion is apt to proje ct from said peripheral portion in correspondence of the side of the support (1 ) resting onto said housings. The invention also concerns an improved process for the production of said optical support (1). |
