Abstract

In magneto-optic recording it is desirable that the read laser power be as large as possible without causing degradation of the recorded information. We have developed a test that efficiently simulates the repeated reading of the recorded magnetic domains. This technique is used to determine the maximum read power and minimum write power of a variety of magneto-optic materials on a variety of substrates. In this paper we report the correlation between maximum read power and the sample’s coercivity and substrate.
