Auric, you are right - we will fix the captioned.
Any comments other then that?

are you (?) somehow related to that story (no joke) of someone inventing a storage medium using a ordinary roll of clear-tape ?
They claimed to have/had a method to use a roll of clear-tape where a laser would write/read on each layer of the roll...since the roll has many it would've ben quiete a lot of data. They also said they did tests with many brands, but the german tesa-tape proved best for that purpose.
I heard that YEARS ago.
Just reminded me by overflying your article and reading about "writing on a multi layered medium"

German and American scientists are working to develop a new information storage technology using ordinary commercial adhesive tape as a medium. Private European Media Laboratory and Stanford University have signed a three-year cooperation contract, EML has announced. A chief goal will be to work together on the storage development; EML expects the project to take about five years to develop.
EML researcher Steffen Noehte discovered some three years ago that the polymer structure of "tesa Multi-Film" brand adhesive tape is well suited as a holographic data medium, the laboratory says. The technique, similar to that used to burn a CD, modifies the optical properties of the tape using a laser. It can store data on any individual layer of the tape without unwinding the roll or disturbing other layers, meaning as much as 10 gigabytes of data can be written on a single roll.
Better Than CD Drives
The laboratory says the new technology is superior to current CD drives, for example, because it is the laser beam that rotates, rather than the storage medium, helping to avoid potential balance problems. This technique enables high-speed rotation and thus allows the high data-transfer rates required to record and play back video, for example.
EML scientists are working with Stanford electrical engineering professor Lambertus Hesselink, an expert on optical and holographic data storage, to further the project, titled "OptiMem." The partners in the project hope to develop a "compact and affordable" storage medium for applications such as pocket computers and digital video cameras. They even envision a data-storage sticker, a modified adhesive film onto which tiny individual holograms are written. It could hold about 250 times as much information as a standard bar code, the researchers say, and could be used as secure identification for products.
