COMPACT DISC AVERAGE TRANSFER RATES
Note 1: The normal CD (at n=1) transfer rate from the disc is 75 blocks per second.
Note 2: The average transfer rates shown are in BYTES PER SECOND.
WHAT IS THE DIFFERENCE BETWEEN CD-R “FIXATION” AND
“FINALIZATION”?
• Fixation is the process of writing the lead-in and lead-out
information to the disc. This process finishes a writing
session and creates a table of contents.
• Fixation is required for a CD-ROM or CD-Audio player to
play the disc. Discs which are “fixated for append” can
have additional sessions recorded, with their own session
lead-in and lead-out, creating a multisession disc.
• When a disc is “finalized” the absolute lead-in and lead-
out for the entire disc is written, along with information
which tells the reader not to look for subsequent sessions.
This final table of contents (TOC) conforms to the ISO 9660 file
standard.
