Roll-Type Optical Advanced Memory with High Recording Capacity

Abstract

We propose newly developed roll-type optical memory (RoCAM). RoCAM is one of the multilayered memories and it has cylinder shape. RoCAM is composed of a recording and transparent layers wound onto a shaft. Five advantageous features of RoCAM are 1) easy fabrication of media, 2) easy implementation of groove structures in RoCAM, 3) parallel recording and reading, 4) rotation stability and 5) constant linear velocity. In this paper, we report advantageous features and one-dimensional parallel signal readout of of RoCAM.
