Abstract
Using local holograms, recording methods on the photothermoplastic (PTP)-carrier with IR- laser heating holographic disk systems with registration of two-dimensional holograms in step- by-step regime and one-dimensional holograms on the moving carrier are developed. Requirements for linear velocity of the PTP-disk are formulated, and an electronic scheme for its stabilization on the whole disk surface is realized. The need for and advantages of one- dimensional microholograms recording with track size d > 200 mkm on the moving PTP- disk are shown. For the first time, qualitative microhologram recording on all surface of moving photothermoplastic disk is obtained. This result supplies PTP-disk capacity of approximately 0,6 Gbit for one-dimensional microhologram recording with disk diameter 133 mm. The use of holographic a PTP-disk as a bank of interconnected weight matrixes in optical implementation of neural networks is suggested.
