CD duplication is, put simply, photocopying, since light (laser) is being used to produce a duplicate. Imagine taking a master disc and making copies of it in a short time. What

What a CD burner does

A CD burner essentially functions as a photocopier. It is either a device that's already built in to the PC or an external writable drive. These days, deskto

The CD burner uses a moving laser much like a regular CD player, except that it not only has a 'read laser', it also has a 'write laser'. The write laser interacts differen

How CD duplication is done

When people say they 'burn' CDs, they mean copying data fr

Which markets to tap where the combination products can do fairly well?
Which combination prod

How to tackle the risks encountered during combination product developmen

A blank CD has a flat, smooth surface, made of a reflective metal layer. Another layer underneath this reflective metal is made of photosensitive dye. This dye is translucent when the

What the blank CD now has is no longer a smooth, flat surface but a surface that has microscopically darker areas which contain a digital patter

Speed matters

The rate at which CDs are duplicated will depend greatly on several things: the

As there is an increasing trend of the combination products companies manufacturing such products should be able to tackle the problems involved in the de
