To most of us, the duplication of a CD is as simple as either dropping off a master CD or seeing how many CDs are in bulk. To those who are duplicating CDs, there is much more to making sure your CD turns out exactly like you want. Specifically, those who are in the business of duplicating CDs will have sessions that are used in order to get all of the details in of your CD. This ensures that everything gets copied off exactly like you planned.
When beginning CD duplication, there always has to be a beginning with how to get the information that you want from the computer to the burner that is being used. When beginning this process, sessions will often be used. This allows for easier movement of formatting as well as the ability to get all of the information in correctly.
The first session that will be done is taking your information and putting it into a specific hardware or software program. This will allow for a completed disk image to be set up as a master copy of what is needed. This will then be paralleled with the information that is in the disk, such as data or music, to be placed into this same master file.
The differences in the sessions for the information is based on the file system that is being used as well as the CD length. For instance, if you have a larger amount of information, it will often be placed into packet writing software, so that it can be divided up equally and not take up a large amount of space on a computer. This will then allow for the information to remain safe in the storage space that it is in.
When the information is being put into the CD, there are also specific parts of sessions that will be used. This begins with defining the different parts of the CD through a table of contents. Each of the tracks will be set up to match the table of contents so that it can be put into the proper place before burned and so that the information can be placed onto the CD in the correct way. This will allow for an easier duplication process and will create a consistency with the copies being made.
After this is done, each of the sessions will be divided by a lead in and lead out for each session. This is defined by the times that are used to duplicate the CD and how this lines up with the table of contents that has been used. For instance, if five tracks are being burned, the session will begin with a lead in, which will prepare the disk for burning the correct information onto the disk. When the specific burning and copying is finished, it will end with a lead out.
The sessions can have as many lead ins and lead outs as needed in order to completely duplicate the CD. This will be dependent on the number of tracks and data that needs to be copied as well as the amount of information that needs to be stored on the software. For instance, if packaging software is being used, it will be easier to have different sessions and to divide the amount of information into several spaces, allowing for the duplication to be processed easier.
The concept of sessions, and the ability to create sessions with CD duplication serves several purposes. The first is to divide up the information in the CD processing as well as to create a separate space for each set of information. The second part of this is to create a work flow that will allow for the information to be finished in a span of time with the CD. If one chooses to use sessions for CD duplication, the process can become easier and allow for more attention to detail.
