METHOD OF MANUFACTURING OPTICAL DISC BY PRESSING AND OPTICALDISC OBTAINED THEREBY |
摘要 |
The invention provides a process for manufacturing optical disks by pressing and disks obtained by such a process, for improving the inherent flatness of the optical disk of the thick type, obtained by a process of pressing between a recorded master and another master, recorded or not depending on whether it is a question of a single or double side disk, this latter being formed from a stack of at least two thin sheets of thermoformable material subjected to a pressure-temperature cycle after which bonding together of the sheets and duplication of the information from the masters for information recording are obtained. |
