Abstract :
Extremely small read heads are needed for stacked-disk and small portable optical data storage devices. Our study has revealed several interesting aspects that can be utilized in the design of compact read heads based on direct optical feedback to a laser diode. Experimental confirmation of our theoretical results is in progress.
