DVD-5 and DVD-10 discs
Single layer, single and double sided disc
formats, which are the easiest to make.
|
DVD-5 (4.7GB)
Single Sided/Single Layer
The DVD-5 is the simplest of the family of DVD discs, comprising
a single layer with a capacity of 4.7GB. Only one of the two 0.6mm substrates contains
data, the other being a blank disc. The two substrates are bonded together to form a 1.2mm
thick disc.
Single sided discs can be printed on by any conventional
method eg screen printing. Alternatively, the blank substrate can be moulded with an image
in its surface and then metalised to make it visible.
DVD-10 (9.4GB)
Double Sided/1 Layer
This disc comprises two sides each single layer. It differs
from the DVD-5 version in that both substrates contain data. To read both sides the disc
will need to be turned over for most DVD players/readers. The capacity is 9.4GB, twice the
single side/single layer version.
Double sided discs cannot be printed except on the hub
inside the lead-in area. Labelling is therefore a problem with such discs.
