概要

• 論文の詳細を見る

• This paper describes new systems for measuring mechanical and optical charac-teristics of optical disks. These characteristics are necessary for designing the head actuator and standard disks for high rotational speeds. The system for measuring mechanical characteristics uses a new lens actuator with high-speed servo perfor-mance. The magneto-optic (MO) signal quality is evaluated by measuring the birefrin-gence effects of the disk substrate. This paper also discusses disk stretch, which is important in considering data reliability at high rotational speeds.
