LabelFlash
The LabelFlash is a technology of engraving of texts and images on the top of the optical disks (CD and DVD) developed by NEC, Yamaha and Fuji, officialized in October 2005 to succeed the DiscT@2 ( Tatoo ).
Principle
This process of certification of discs makes it possible to personalize the DVD so as to recognize them easily, by engraving the images with the back of the disc. The purpose of it is to replace the traditional self-stick labels, the inscription with the felt, or the jet impression of ink, which require a whole a specific material; here, indeed, the engraver becomes the only necessary tools. It is enough to engrave the data, to leave the disc to turn over it and engrave the label on the other face.
The technical process consists as for the DiscT@2 modifying the use of the Laser, which instead of engraving binary data by a succession of hollow in surface of the disc (encoding by Modulation), serious the disc to produce the dark zones of the image.
Just like let us note that this technology allows, the DiscT@2, to also engrave the face containing of the data, on peripheral surface not used by these data.
Characteristic
The image is engraved on a sharp blue bottom, in range monochromic.
Engraving requires from 5 to 25 minutes, according to the quality and the extent of the model of label.
Disadvantages
The DVD used owe necessarily beings compatible with this technology to profit from this certification, contrary to the old technology DiscT@2 from which LabelFlash derives, but just like the competitor LightScribe.
The legibility of the label depends on the conditions on illumination, contrary to the technology LightScribe which uses a matt sensitive layer which makes the image clear in all circumstances.
