Abstract
In this paper we report an optical head developed for measuring characteristics of magneto-optical disks. The features of this head are followings:-
(1) Collimating system without anamorphic elements.
(2) Small phase retardation in signal-readout optical system.
(3) Differential readout method using two photodetectors.
