How is a DVD made?

Answer 1

The first step in manufacturing a DVD-R or DVD+R disc is to fabricate the polycarbonate plastic substrates (incorporating the spiral groove and land pre-pits) using an injection molding process.

The dye is then applied using spin coating and the metal layers by means of DC sputtering. After both sides of the disc are completed they are bonded together using a hot melt, UV cationic or free radical process. Additional decoration or printable layers are typically applied using screen printing methods.

A DVD-R (General) disc undergoes a further manufacturing step in which a specialized computer DVD recorder is used to "prewrite" information in the Control Data Zone of its Lead-in Area to inhibit direct copying of prerecorded DVD-Video discs encrypted with the Content Scrambling System (CSS).

Apart from this, and some minor differences in the configuration of the molding stamper used to create the substrates, the process for manufacturing DVD-R and DVD+R discs is virtually identical.

Easily create professional looking DVD case inserts by choosing insert sets available at office supply stores that can be imprinted using your home computer and printer. Achieving the best results is partly linked to picking the correct card stock for your project. # Step 1 # Choose printable DVD case inserts that are compatible with your printer. Some are only compatible with either an inkjet or laser printer; however, others are compatible with both. For easier printing, look for inserts that include templates that are compatible with your word-processing software as well. # Step 2 Pick inserts that are made from sturdy card stock with a bright white finish. Look for inserts with matte surfaces that are advertised to deliver a high ink absorption rate. Images and words printed on such inserts look cleaner and sharper. # Step 3 Print photos on photo-quality inserts. For best results, look for inserts that offer hi-resolution output at 720 dpi and higher. # Step 4 Make sure the DVD case inserts to be printed are surrounded by deep perforations that are clearly visible from the front and back. The inserts will be attached to a sheet so that it can pass through a printer. Deep perforations allow for easy removal of the inserts from the pages. # Step 5 # Buy inserts that are already scored in the middle so they can easily be folded when they are placed inside the DVD case. Some inserts are designed as four-page booklets that fit under the tabs inside a standard case. Such booklets help prevent crowding a lot of information onto a typical DVD insert.
