(Blog forum) How to Prepare CDs Like a Pro
No commentsBy Marlin Rollins
The master CD or DVD disk, is the one you will provide to your CD or DVD vendor for either replication or duplication of the media. Below, you will find some tips designed to help you create a high quality master disc:
1. Always use the highest quality media that you can obtain, as all media isn’t the same. Do your research, take your time, then choose a brand that will produce a high quality disc each and every time you duplicate or replicate.
2. Avoid copying from a network source. If the source files for your disk are on a network drive, copy the files to your local disk before you burn a disc. If you can’t move the files to your local drive, try using the copy to hard drive first feature. When doing this, your burning software will create a temporary image file during the burning process. Once the burning has been completed, the temporary file will be deleted.
3. You should always avoid burning on a laptop computer that is running on low battery power. The fluctations that will occur in the available battery power may cause you to have poor results in your duplication.
4. Always make sure that you finalize your disc. If you fail to finalize, the disc won’t play back. Finalizing will also help increase the reading compability in other CD-ROM drives.
5. Never use the packet writing method to burn a master disc. This method is very common with burning drives that have re-writing capabilities. This method will produce discs that can’t be read on many CD-ROM drives.
6. Avoid any type of impact or movement of the drive during burning. Doing so can cause the laser to skip or jump tracks, which will lead to errors or a bad disc.
7. If available, use the “burn-proof” feature. This feature will allow the drive to slow down the burn speed in the event the computer can’t supply the data fast enough. Although this can increase the burn time, the quality of the disc will be much better.
8. You should avoid having multiple applications open when burning, especially those that access the Internet or a network. This can hinder your computer’s ability to supply data to the burner drive at the necessary rate.
If you follow the above tips, you should produce a master disc of excellent quality. A master disc is something you’ll want perfect, which is why you shouldn’t take any risks.

CD Duplication: Things to Consider
By Marlin Rollins
The process of writing data to a recordable CD can be a complex process, as it demands a lot from both hardware and software programs. Much of this complexity is hidden from the user by the program, although you should be aware of these factors.
Data The total amount of data you are writing is much less important than whether or not it contains large or several small files. If there are a lot of small files, the system may have problems with locating and opening the files quickly enough to send them smoothly to the CD recording drive.
The computer Any interruption that may occur is fatal to CD duplication, so you should ensure that your CONFIG.SYS and AUTOEXEC.BAT don’t load any TSR utilities which may interrupt operations. Screen savers, alarms and reminders, or incoming faxes may also kill disc writing. You should also turn off network sharing so no one will access the files that you are trying to write, as this could also kill your disc recording.
Hard Disk Speed To write an image to the CD, the hard disk from which you are writing must have a transfer rate that is fast enough to keep the memory buffer full in the CD recorder. This normally means an average hard disk access time of 19 MS or better.
Defrag If your hard drive has to search everywhere over a fragmented hard drive for the data to be written, it can cause the operation to slow down or even cause a fatal error. Therefore, always be sure to fragment your hard disk drive.
Recording speed Most new CD recorders and even some older ones, are capable of writing at two (sometimes even four) times the standard playback. It should be possible for you to select the speed; as even though fast recording is a time saver, it can also cause some bad situations.
When you copy an ISO (image file) from the hard disk to a CD, the speed is rarely a problem as the image is already one large file in which the files and structures are already in order and divided into CD-ROM sectors.
When you write from a virtual image, things can get a bit trickier. In order to copy to CD, the program must consult with the database to find where each file should go in the image and where it is actually stored on the hard disk drive.
Then, it must open the file, divide it into CD-ROM sectors, at the same time sending the data in a smooth continuous stream to the recorder. Locating and opening the file is a bit more time consuming, as writing is more difficult if you have a lot of small files.

CD Mastering: The Essentials
By Marlin Rollins
Even though many assume that the mixing of the seperate audio tracks is the final step, a recording should always be mastered well in order to sound great. CD mastering is the final chance for creative input when you create a compact disc. After the discs has been mastered, it can be printed, reproduced, and then sold.
The process of mastering a CD actually involves several steps. The first step is putting the songs, or tracks at this point in the correct order. The length of time between the songs is also adjusted, along with the editing of the songs. Any unlisted or secret songs on the CD are normally added at this point as well.
There are several ways that you can go about mastering a CD. First of all, the mix can be sent to a professional CD mastering engineer, which is what professional musicians normally decide to do.
The mastering engineers will often work in their own mastering facilities, which are very different from standard studios, in the fact that they have much less gear and are designed for the best possible playback of the mix as possible in order to fix anything that’s wrong.
Aside from mastering engineers, CDs can also be mastered at home using computer software. This option is normally more realistic for unsigned artists or musicians who are just starting out with their music. Depending on the software quality and skill of the individual doing the mastering, the CD may turn out perfect or it may sound very unprofessional.
You can also refer to online CD mastering as another option. Cds that are mastered online can be great, as instead of sending a mix to a mastering engineer, the mix is instead sent via the Internet. To do this, you’ll need a high speed Internet connection.
The cheapest way to go about mastering a CD is with free mastering. Artists and musicians may choose to use free mastering programs with demos or other earlier recordings that artists will use to send to major record labels to generate some interest in their music.
The major differences with a professional CD and an amateur recording is normally found in the mastering. Every song that you hear played on the radio is thoroughly mastered in order to sound better.
While you can master using free programs or your computer, a professional CD mastering engineer is normally the best way to do business if your band is looking to make a profit from your music.
