Burning CDRs

CD-R media are an extremely popular means of exchanging moderately large files. Most CD-R and CD-RW media hold 700MB of files (older discs held 650MB), while recordable DVD formats have capacities of several gigabytes. Plain write-once CD-R discs cost $0.50 or less and are likely to remain readable for several decades, given proper storage, so they're an excellent low-cost archival medium. You can't simply mount a CD-R disc and write files to it as you would a floppy disk, though; you must create a complete filesystem and then copy (or burn) that filesystem to the disc. This process requires using two tools, mkisofs and cdrecord; or variants of or front-ends to these tools.

Note This section describes creating CD-Rs. To read a CD-R, you can treat it like a CD-ROM and mount it using a standard removable-media mount point, as described earlier in "Creating /etc/fstab Entries for Regular Access." CD-Rs created by Macintosh users sometimes use HFS, so you might also be able to use HFS Utilities, as described in "Using Access Programs for Quick Access."
