Archiving imagery on digital optical tape
Methods and apparatus for archival storage of an image are disclosed. The image may be separated into a plurality of bit plane images. The plurality of bit plane images may be written separately onto digital optical tape.
1. A method for archival storage of digital image comprising one or more color component digital images, the method comprising:
separating each of the one or more color component digital images into a respective plurality of bit plane images;
writing each of the bit plane images separately onto digital optical tape;
generating fiducial markers; and
writing the fiducial markers onto the digital optical tape concurrently with writing the bit plane images.
2. The method of claim 1 , wherein the image is a color digital image and the one or more color component digital images consist of red, green, and blue color component digital images, the method further comprising:
converting the color digital image into the red, green, and blue color component digital images.
3. The method of claim 1 , wherein the image is a color film image and the one or more color component digital images consist of red, green, and blue color component digital images, the method further comprising:
converting the color film image into three black and white film images representing the red, green, and blue color components of the color film image;
digitizing the three black and white film images to provide the red, green, and blue color component digital images, respectively.
4. The method of claim 1 , wherein the image is a black and white film image and the one or more color component digital images consist of a single color component digital image, the method further comprising:
digitizing the black and white film image to provide the single color component digital image.
5. The method of claim 1 , wherein writing each of the bit plane images separately onto digital optical tape further comprises:
writing the bit plane images onto the digital optical tape sequentially.
6. The method of claim 1 , wherein writing each of the bit plane images separately onto digital optical tape further comprises:
writing two or more bit plane images side-by-side on the digital optical tape.
7. The method of claim 1 , further comprising writing metadata onto digital optical tape concurrent with writing the bit plane images and the fiducial markers.
8. An apparatus for archival storage of a digital image comprising one or more color component digital images, the apparatus comprising:
a memory to store the one or more color component digital images;
an optical media recorder
a controller configured to:
read each of the one or more color component digital images from the memory as respective pluralities of bit plane images;
generate fiducial markers;
control the optical media recorder to write each of the bit plane images separately onto digital optical tape; and
control the optical media recorder to write the fiducial markers onto the digital optical tape concurrent with writing the bit plane images.
9. The apparatus of claim 8 , wherein the image is a color film image and the one or more color component digital images comprise red, green, and blue color component digital images, the apparatus further comprising:
a color separator to separate a color film image into three black and white film images representing the red, green, and blue color components of the color image; and
a digitizer to digitize the three black and white film images to provide red, green, and blue color component digital images, respectively.
10. The apparatus of claim 8 , wherein the image is a black and white film image and the one or more color component digital images comprise a single color component digital images, the apparatus further comprising:
a digitizer to digitize the black and white film image to provide the single color component digital image.
11. The apparatus of claim 8 , wherein the controller is configured to control the optical media recorder to write the bit plane images onto the digital optical tape sequentially.
12. The apparatus of claim 8 , wherein the controller is configured to control the optical media recorder to write two or more bit plane images side-by-side on the digital optical tape.
13. The apparatus of claim 8 , wherein the controller is configured to control the optical media recorder to write metadata onto the digital optical tape concurrent with writing the bit plane images and the fiducial markers.
