Abstract

A compact magneto-optical disk head, integrated with chip elements and optical parts, using a hybrid assembly technique, has been developed. Optics and beam splitter characteristics were optimized so as to realize both compact size and sufficient read out characteristics. More than 46 dB C/N ratio and stable operation were achieved, while simple optics and an easy assembly method were used.
