Abstract

Basic operation of new multifrequency three-dimensional (3-D) optical read-only memory (ROM) disks has been demonstrated experimentally. Several types of metallic island film exhibiting a selective resonance absorption in a visible–near infrared region are used as recording layers on the 3-D disks. The monochromatic light with a suitable wavelength near the resonance wavelength of each layer is used for the readout of information. We demonstrate that bar-code patterns recorded in silver and copper island layers can be read by using transmitted or reflected light. Furthermore, we also show that the 3-D disks with ≥ 3 recording layers can be realized.
