Abstract
This paper describes a new method for measuring optical disk mechanical characteristics significant for both drive design and disk interchangeability. This method enables the simultaneous and accurate detection of disk properties using a compact measuring head. This paper also discusses a new acceleration criterion for optical disks and an appropriate clamping force for correct measurement of their mechanical characteristics.
