High capacity recording device having high density recording media

摘要

A high density recording device includes a memory medium (10) formed by layering an insulating film (12) on a silicon substrate (11). Information is written to the medium (10) by applying voltage to the insulating film (12) to form a low resistance micro-domain. To read the device, a detector (20) is used to detect the lowered resistance of the insulating film (12).
