Abstract

Multi-layer write-once optical disks with tellurium suboxide palladium-doped phase-change recording films were designed and adopted to read/write utilizing a violet laser. A dual- layer medium showed carrier to noise ratios (CNRs) of more than 50 dB within a laser power of 7 mW at a linear velocity of 5 m/s in each the condition of numerical aperture (NA) equals 0.65 and NA equals 0.85, which corresponds to a recording capacity of 27 GB and 45 GB on a dual-layer disk of (phi) 120 mm in diameter, respectively. Furthermore, a quadruple-layer medium showed CNRs of more than 48 dB within a laser power of 12 mW at a linear velocity of 5 m/s in the condition of NA equals 0.85, which corresponds to a recording capacity of 90 GB on a quadruple-layer disk of (phi) 120 mm.
