Abstract

This paper presents a comparative study of magnetic circular birefringence (MCB) to magnetic circular dichroism (MCD) detection of the Kerr effect in a magneto-optical head with circular polarized light incident on a Co/Pt superlattice medium. Results show that the MCD system can deliver a CNR of 40 dB despite the loss of in capability to reject common mode noise, which is less than the requirement for error-free recording. Thus it can be applied only to systems that can tolerate a higher bit error rate or operate at lower data frequency.
