A photo paper which uses DVD Rewritable technology to print extremely crisp monochrome photos. The paper has a dye layer that can be changed from light to dark and back by a high power laser. Whereas DVD labeling/unused space printing uses blank DVDs, this would use special paper (actually plastic in
the shape of a photo) and a laser beam. The resolution would be 1 bit 32,000 DPI.

Mono and polychrome versions available - few commercial applications exist, with the exception of a couple of handheld text-readers from Sony. [zen_tom, Oct 30 2006]
Xerox Seeks Erasable Form of Paper for Copiers

The researchers describe the invention as being based on compounds that can change color when they absorb a certain wavelength of light, but can then gradually revert to their original appearance. The compounds currently self-erase in about 16 to 24 hours, or can be erased immediately when heated. [xaviergisz, Nov 27 2006]

Sounds like you're describing a thermal
printer, to me. |
|

There's that new lcd paper stuff - and it works without all those lasers - I don't know what the resolution is though. |
|
| |
kudos, best idea I've read in quite a while. |
|
| |
Because of the ultra-fine resolution, you may also be able to print diffraction patterns and holograms. |
|
| |
However it may be difficult to implement. In a DVD burner the read/write laser only has to move on a single axis. This invention would require fine motor control in 2 axes (assuming you're talking about rectangular media without a big hole in the centre). |
|
| |
Note for searching for similar inventions: printing on the blank space of DVDs with the burner is also known as 'pit art'. |

Fair point, Ian, but it'd be surprised if laser
solutions aren't amongst those being
considered in the many possible products
that fall under the heading of epaper. |

Toshiba just annouced the release of this today. "Paper" is reusable 500 times and only costs £5 per sheet..... |

// reusable 500 times and only costs £5 per sheet..... // |
|
| |
Which works out at GBP£0.01 per print, in 2006. |
|
| |
Current (2017) prices for basic white A4 paper are around GBP£0.005 per sheet. |
|
| |
It would be worth finding out what the current economics are - they might be more favourable by now. |
