摘要

We have designed a dual-beam magneto-optical (MO) storage system to test the dynamic storage properties of MO disks. The characteristics of this dual-beam system are demonstrated. Magnetic field modulated direct overwrite, which is a promising technique for high-speed MO storage, is realized on TbFeCo MO disks with this dual-beam MO system. The effect of light intensity, magnetic field intensity, and linear velocity of the disk and the modulating frequency variation on carrier-to-noise ratio is investigated. # 1997 Society of Photo-Optical Instrumentation Engineers.

Paper 40106 received Oct. 31, 1996; revised manuscript received Apr. 8, 1997, and May 3, 1997; accepted for publication May 5, 1997.
