CD copiers can usually burn only one copy at a time. After one CD is copied, the user has to manually open the drive shutter (or press a button provided for that purpose) and replace it with another blank CD for copying. This makes copying CDs with a manual PC copier a slow process.
Automated CD copiers make the burning process much quicker. These have an input spindle and an output spindle. Blank CDs are placed in a stack on the input spindle. A robotic arm picks up blank CDs from the input spindle, one at a time, and sends them into the drive for copying. When the burning process is over, the CD is automatically placed onto the output spindle. This is a hands-free process, but it takes a long time to complete the process.
These automated CD copiers are ideal because the CD copier can be left running overnight or a weekend. A large number of CD or DVD discs can be stacked on the spindle, and the machine can be left to run until the job is complete.
