概要

• 論文の詳細を見る

• A new method for recording tamper-resistant and disc unique information to each ROM disc is proposed.A pulsed beam of the CW-Q switch type YAG laser is irradiated to a ROM disc.A laser spot is formed like a rectangular shape on a reflective film of the disc and removes it to form a stripe of 10μm width overlapping on pre-pits.By forming a series of the stripe on the disc circumference according to the phase encoded signal, 188-bytes information can be recorded.The recording method has been adopted as BCA (Burst Cutting Area) in the DVD standards.
