Near-field optical recording using magneto-optic, phase-change, and photochromic materials was reviewed. Among them, rewritable recording using photochromic media was described in detail. Marks as small as 100nm in width were recorded on the dithienylethene photochromic media by irradiation with 529-nm light, and erased by irradiation with UV light (300nm < λ < 400nm).
