概要

• 論文の詳細を見る

• We have realized the readout of optical disks with 6 times higher areal density than that of conventional compact discs (CDs). This system uses a new variable-length block code variable five modulation (VFM) and an optical pick-up with a miniature integrated diode-pumped second harmonic generation (SHG) green laser (mi-green laser) and a 0.6 NA objective lens.
