1. What's is UDF format?
UDF format is a newer CD-ROM file system standard that's required for DVDs. The format is meant to be a replacement for the ISO9660 file system used on today's CDROMs, but the immediate impact for most will be DVD. DVD multimedia CD-ROMs use the UDF file system to contain MPEG audio and video streams. To access DVD CD-ROMs, you would need a DVD CD-ROM drive, the kernel driver for the cdrom drive, MPEG video support, and a UDF file system driver. See the Livid project for news and software for playing DVDs. UDF can also be used by CD-R and CD-RW recorders for packet writing. By using packet writing, CDs can be written more efficiently, in both the disk space used and the time to write the CD. Adaptec DirectCD is a Win95/WinNT example of packet writing, using the UDF version 1.5 file system.
2. What's is Packet-writing?
This method allows you to write data to a CD in small increments, instead of large blocks, as with the disk-at-once and track-at-once methods. This method eliminates the session closing overheads inherent in the multi-session method of adding data to a disk in more than one write session. However, you cannot write CD-DA, also known as Red Book, audio disks using packet writing. With packet writing, you can use your CD-R just like a hard drive. With packet writing, you do not need to open or close a session each time data is written, which means even the CD-R novice should be able to copy data to CDs with relative ease.
