Well, someone liked the idea. Anyone have any comments, or any idea of the feasibility? |
|

Notg my bun, but sounds like it ought to
be doable. |

Im intrigued by this, and wonder if some combination of chemicals could prove to be more durable than current metallized discs. Maybe so. I am familiar with photographic processes for masking (sandblasting glass, and silkscreening), but the unexposed parts of the mask must be processed further (rinsed away) to reveal the areas that have set. Otherwise, it's identical to an undeveloped sheet. |

You must keep the discs protected from light until the entire process is complete. Unless the drive holds a spindle in the dark, the CD-ROM blanks must be individually packaged. Human eyes cant detect ultra-violet or infra-red, so if a disc is damaged by radiation from any source, you dont know until youre done and try to read it. Try to write to an ordinary CD-ROM that has flaws, and you know during the write process. Its not a criticism, just an observation that these will require special handling. I cant just keep my blank CD-ROMS strewn out on the lawn anymore. |

What happens to the chemicals as they react to the radiation to make the drive able to read the data? Is there a color contrast or reflectivity change? |
