What does ISO 9660 mean?

Answer:

It is an international standard describing the file structure for computer files on compact disc. You should use this standard when sharing files on a CD between two different operating systems, Mac and Windows for example. File names are can be up to 8 characters long plus the 3 character extension (example - bobslist.doc). Most recording software should allow you to change the file system from Joliet to ISO 9660 (PC) or HFS to ISO 9660 (Mac).

What does Joliet mean?

Answer:

Joliet is an extension of the ISO 9660 standard, developed by Microsoft, to allow CD discs to be recorded using long filenames. Joliet allows you to use filenames up to 64 characters in length, including spaces, when recording files to a CD disc. Joliet will also record an associated DOS-standard name for each file so that the disc may be read on DOS systems or earlier version of Windows. If you select the Joliet option, filenames up to 64 characters long will be allowed.

What are buffer underruns?

Answer:

CD writing is a real-time process, which must run constantly at the selected recording speed, without interruptions. The CD recorder's buffer is constantly filled with a reserve of data waiting to be written, so that small slowdowns or interruptions in the flow of data from the computer do not interrupt writing. A buffer underrun error means that for some reason the flow of data from hard disk to CD recorder was interrupted long enough for the CD recorder's buffer to be emptied, and writing was halted. If this occurs during an actual write operation rather than a test, your recordable disc may be ruined.

What does 'Multiread' mean?

Answer:

The importance of MultiRead is determining whether the CD-ROM drive can read all CD formats including CD-RW discs. Older CD-ROMs manufactured before the MultiRead specification are unable to read CD-RW discs or UDF written discs. For more information on the MultiRead and UDF standards, please visit the OSTA (Optical Storage Technology Association) website at: http://www.osta.org

What is 'ripping'?

Answer:

Ripping or Digital Audio Extraction (DAE) is recording a song from your CD to your computer. In order to rip songs your CD-ROM or CD-Recorder will need to be capable of Digital Audio Extraction.

How do I convert my MP3 and Wav files to CD-DA format?

Answer:

First you'll need to determine whether your current software will convert from either MP3 or WAV to CD-DA format. Most pre-mastering software will convert WAV files into CD-DA format automatically. This is true as long as the software is set to create an audio disc and not a data disc.

Some pre-mastering software has the ability to decode MP3 into CD-DA fomat on the fly. This means you won't need any additional software to convert MP3s to listen to them on your stereo. If your software is unable to convert MP3s to CD-DA, you will need to search the Internet for decoder software. This will allow you to convert an audio track or song from MP3 to Wav. You will then be able to record the Wav file from your computer to a CD using the recording software.

Please record responsibly. Before copying anything onto a CD-R or CD-RW disc, please be sure you are not violating Copyright laws. Most software companies allow you to make a back up or archive copy of software. Check your software license agreement for specific details.

How do I eliminate the two second gaps between audio tracks?

Answer:

Usually, audio tracks are recording in track-at-once mode within the software, which leaves a two to three second gap between each track. In track-at-once mode, the laser turns off after the track is completed, and the result is the gap in recording. This gap can be eliminated by recording in disc-at-once mode with the pre-mastering software. When using track-at-once, the laser stays on through the entire recording session.

What is Optimum Power Calibration (OPC)?

Answer:

The OPC is the laser's power setting as it burns a CD. Each CD Recorder has a unique OPC setting. It is a measurement of the strength of the laser. The OPC circuit calibrates the laser at the beginning of the CD, and then uses the specified laser power through the entire session.
