Three-dimensional pit selection (3DPS) is proposed for optical discs with the capacity of hundreds of gigabytes, where the super-resolution and multi-layer techniques are combined. In this method, a high transmittance of each layer is obtained by discrete opaque data pits made of a super-resolution material. The dual-layer disc was fabricated using a phase-change material as a pit material. The experimental...
We demonstrate 80 nm diameter bit recording for the first time using a phase change recording film and a reflection scanning near-field optical microscope with a 785 nm wavelength laser diode. The sample structure was a 20 nm thick ZnS SiO 2 protection layer/30 nm thick Ge 2 Sb 2 Te 5 recording film/150 nm thick ZnS SiO 2 protection layer/polycarbonate substrate...
Scanning near-field optical microscopy (SNOM) was applied to phase-change (PC) mark writing to investigate the potential of ultrahigh density data storage. GeSbTe, one of the typical PC media, was used as a recording layer. Using a laser diode (LD) with a wavelength of 785 nm as light source, crystalline marks with a minimum size of 80 nm in diameter were successfully written in the amorphous...
