Abstract
Important factors in read and write processes for magnetooptical disk are that readout carrier to noise ratio (C/N) is high, readout signal envelope is smooth,optical efficiency is high, head size is compact and head weight is light. This paper summarizes results from many studies on optical retardation influence in magneto-optical head and disk substrate. Improvements in a magneto-optical head and disk drive system are presented.
