TOC INDEX

•Recording Type.

Track-at-Once.This is the default. For track at once, the laser is turned off after each track, which produces a two-second gap. The track-at-once feature, enables songs and data to be written at different intervals. The lead-in sectors that are written at the beginning of each session contain the location where additional data can be placed on the disc.

Disc-at-Once.If this option is checked, the lead-in, all the tracks and lead-out are written in same action. The laser is kept on for the entire session.

•Closed-Finalized/Open. A closed disc means no additional data can be added. If the disc is left open additional data can be added in another session.

•File System. The file system is the method by which the files and folder are arranged on the burned disc. Joliet is best for most CD burning applications. UDF 1.02 is best for DVD burning. UDF 2.6 is used for Blu-ray. The recording engine can also add a bridge which effectively adds another file system to the disc. UDF 1.02 with a Joliet bridge is the default.

Most of the differences between file system types relate to file name length and character restrictions and folder level depth. ISO is the most restrictive and oldest and UDF is the least restrictive newest file type. The complete list of speci- fications for each is several hundred pages. Macs and PCs can read both types.

If you would like to make your burned disc compatible with very old operating systems or other less popular oper- ating systems use the ISO system.

•Test Record. If this option is checked the recorder tests a disc for record ability before burning. The drive laser is set to read power and the entire surface is scanned for errors. This takes the same amount of time as recording. (DVD+R media cannot be tested) This options can not be used in combination with normal recording or verify.

•Verify. If this option is checked, it compares the copy with the master bit for bit. If it finds a discrepancy it rejects the disc. Verify is an extremely high quality standard. If the disc is audio or video, the discs may still be playable and the errors may not be detectable by human eyes or ears.
