Labelflash and its Functions

A technology developed by Yamaha Corp. and Fuji Photo Film Co. that enables consumers to burn images directly onto a special dye layer on a disc, using the same laser used for data recording. To burn images and text, you must use the complete Labelflash system which consists of special Labelflash DVD media and a recording system which supports the labelflash function. Labelflash technology burns the image 0.6mm deep into the media in as little as five minutes.

General Specifications of Labelflash Disc:

Depth Picture burning layer - 0.6 mm from the disc surface

Dye for Picture burning layer - Organic dye

Picture burning area - 25mm to 58 mm

How it works

Generally, a burning function will supply a DVD recorder with raw digital data, to which the recorder's hardware insert header and error rectification information and then converts it into the so-called eight to sixteen (EFM+) modulated patterns. These are the little portions of data that get written to the disc exactly like printed labels.

The altered patterns for DVD writing differ from a minimum value to a maximum value. A grouping of these patterns, is used for writing to DVD-R and DVD+R. The result is that the flamed area looks gloomy than the unused area. LabelFlash takes things in advance and breaks free from the limitations forced by normal modulated patterns. This permits more flexibility in how the laser burns onto DVD recordable media, making the creation of visible images possible.
