How to make DVD-discs (30 photos)

Photographer Andrew Manuilov was sure that the information on any drive is always recorded. As it turns out, no. Once on a single plant in Kazakhstan for production of optical media LaserMaster, he learned that the information on the disc is literally imprinted. But see for yourself



Production CD - process is fully automated, but watching him chief engineer Sergey Votintsev



Optical discs are made of polycarbonate, which is supplied to the factory in huge sacks



That is - the future drives!



Bags of pellets go first in the drying device ...



after which the tubes are directed into the molding machine where it is heated to a liquid state ...



... And injected under pressure into a mold in which the stamper is



Stamper - a metal plate with the exact image information. Here in this thing, and is a film that later transferred to the disk. We stamper has another name - matrix. By the way, no one would have allowed you so simply take the matrix in the hands - I think that it immediately end



At a temperature of 250 degrees is heated to liquid state polycarbonate, takes the form of a disc. And the information applied to the matrix is ​​imprinted on it



The first 30 pieces each draw automatically reject to ensure the stability of subsequent casting



The blanks with information received in the cooling unit where their temperature falls to room









Then they are covered by a reflective surface (metallization) so that later laser beam in your player can read the information on the disk. Without this coating laser simply pass through



Then blanks are glued together by a transparent glue that is unwound over the surface of the centrifuge for uniform gluing. DVD-wheels consist of two layers, a CD - one



While this is a semi-products



Disk surface test is performed with a laser. Of the 40 drives the car has rejected one. Minimum party of one of the film - 500 discs. Manufacturing period of 14 days, the capacity of the plant is 300,000 discs per month



Once printed one batch of films, it is sent to the painting. At this time, you can run another batch of films



This process next novel Gordeev, the operator of the printer, whose mission - to achieve an exact match of the customer received the label layout



Ready drives come in a temporary warehouse, where all are in alphabetical order.



Irina, accounting manager, prepares a complete set with the task - and printing discs for subsequent assembly





Each disc is accompanied by a hologram



First, a DVD-box printing is inserted, then the disk. Girls do it with incredible speed



Collected wheels fall on the machine where packed in cellophane film



And only then collected in boxes and sent to the distribution center



From there, the goods of daily expenses shop all over Kazakhstan



Now the boxes are shipped to the store "Grand listen to anything", located on Gogol Street Almaty



At all stages, made a careful control over the safety of all intellectual property from possible leaks



Happy viewing!
