CD manufacturing

CDs revolutionized the media industry when they first reached the market in the early 1980s. Ever since we were assigned our first CD replication project, Riyan optical has been an industry leader in staying atop of the latest CD ROM duplication and audio CD manufacturing technologies to ensure that your vision gets to market in the most efficient way possible.

 Every phase of your CD replication project will be executed with the utmost care and precision and with complete accessibility for you thanks to our multi-tiered service system. Your project will also be monitored from the checking of your master, to glass mastering, all the way until shipping and delivery.

After top-quality CD replication at incredible turnaround times, we can add to your CD ROM or audio CD those perfect finishing touches-CD silk screening, labeling and custom CD packaging. The Philips CD specification for CD Audio and CD ROM formats defines the maximum playing time as 74 minutes and 44 seconds, or 650 MB. Riyan optical will accept masters of up to 76 minutes. Longer playing times of up to 79 minutes may be possible but we cannot guarantee that the disc will play satisfactorily in all CD players/drives. Where the length exceeds 76 minutes


CD duplication

CD duplication is where we copy the data to your discs using lasers, just like the CD writers in most PC's today. This is ideal for low volume orders from 1 to 500 units. Because there is only a small setup fee it keeps the costs down for each CD


CD replication

When you are looking to produce 500+ CD's we recommend 'Replication'. When replicating discs we make a master to mold your discs against, this process incurs a larger setup fee but allows us to manufacture each disc at a lower cost per unit. We also use duplication for express orders that need delivering in under the 8 days required for replication

Your data, whether software, music or marketing presentation, is transferred to a glass master which is used to create a metal stamper, the stamper is then mounted onto the disc moulding machines. The CD replication process works in two stages, first polycarbonate plastic pellets are injection moulded into the shape of your completed disc, then molten aluminium is sputtered to the back surface of the disc creating the reflective layer that makes the disc work when read by the player's laser. Your information is stored on the disc as pits in the polycarbonate surface.
