Packet Writing
This method is used to record data onto a disc on a file-by-file basis. This
method divides a track into small segments called “packets” so that data can
be written on a packet-by-packet basis, which means that you can record
data in much the same way as you copy data to a floppy or hard drive by
dragging and dropping it on your desktop. With such convenience, Packet
Writing is suitable for daily data backup. Packet Writing also allows you to
add packets to a disc as long as there is free space left on the disc.
• Discs need to be formatted before use.
• Formatting a CD-RW, using packet writing software, reduces its storage capacity
(rated capacity printed on the disc) by about 100 MB because disk space is
required for packet writing itself.
• For CD-R discs, deleting data means masking data but not actually removing data.
Therefore, deleting data from a CD-R does not increase free space on it.
