Let's take a trip to an optical medium factory in Kazakhstan where you can have a clear idea how movie DVDs are produced.
For a start, the process is fully automatic; the chief engineer merely keeps an eye to it.
Optical discs are made of polycarbonate that comes in large bags.
Here they are – future DVDs.
The granules first get into the drying machine.
And then get heated till they become liquid mass....
...which then gets crammed into a press-form with a stamper inside.
The stamper or matrix is a metal plate with precise information. This one is a movie which will be on a DVD in a while.
Under the temperature of 250 degrees liquid polycarbonate gets shaped into a disc. And the info on the matrix gets imprinted on it.
Workpieces with information get into a cooling machine.
Then they get covered with reflecting surface so that laser ray could read the info.
Half-finished products.
Laser test rejected one copy out of 40.
After one lot has been produced it gets painted.
A room used as temporary storage.
Preparing the covers.
Every DVD goes with a hologram.
These women prepare DVD boxes.
Wrapping the boxes with cellophane film and putting them into boxes.
From this distribution center DVDs are delivered to the stores all over Kazakhstan.
Checking the employees who have access into the production plant.
Have a nice time watching DVDs!
