概要

• 論文の詳細を見る

• We optimized BiFeO thin film for use in multilevel optical recording. Due to minimal intersymbol interference (ISI), we obtained a 2.57% sigma-to-dynamic range (SDR) at a recording capacity of 25 GB. We confirmed that our write-once disc achieved a recording capacity of 25 GB using a laser diode with a 405-nm wavelength and a 0.65-numerical aperture objective lens.
