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 handiness, Packet Writing is suitable for daily data backup. Also,
Packet Writing allows you to add packets to a disc as long as there is free space left
on the disc.
Notes
• Discs need to be formatted before use. Packet Writing allows you to delete data copied (written)
on a disc. For CD-RW discs, however, added data is written successively in areas freed up by
deleting other data, so that you can record data any number of times until the disc fills up.
• Formatting a CD-RW, using packet writing software, causes its storage capacity (rated capacity
printed on the disc) to reduce 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. Data can be erased and rewritten
100 times maximum.
