A compact disc is a storage medium that can store data in any format. Depending on the type and production technology, they can contain a different amount of data. The discs are made of polycarbonate with further application of a metal base. All information from the carrier is read using a laser.
Instructions
Step 1
First, polycarbonate granules enter the plant and are loaded into a special drying device. After that, they are fed to the injection molding machine, where they are heated to a liquid state.
Step 2
Liquid polycarbonate is poured into a special press, where a device called a stamper is located, which is a metal plate with an image of the information that needs to be recorded on it. The material heated to 250 degrees takes the form of a disk, and information in the form of microscopic depressions is imprinted on it.
Step 3
The workpieces are cooled to room temperature on a special cooling unit, after which they are covered with a reflective surface made of metal. This is done so that the drive's laser can read the recorded information.
Step 4
The surface is tested with a laser. If the device reads the data recorded on the medium, the disc is sent for painting, where a pattern is applied using special equipment. The media is then packaged, sent to the distribution center, from where it is delivered to customers or stores.
