ABSTRACT:
A data storage apparatus includes an array of optical fibers. The array has a first end and a second end. The first end of the array includes multiple optical fiber ends, each optical fiber end having an end face adapted for receiving light of a wavelength λ into the fiber for conveyance to the second end of the fiber array. The second end of the array includes multiple tapered optical fiber tips, each tapered optical fiber end having a minimum diameter less than λ. An opaque coating covers a portion of the tapered optical fiber tips. The data storage apparatus also includes a photochromic medium located within a distance λ of the second end of the array.
