5.1.3.CD-R / CD-RW Data Configurations Before writing

CD-R / CD-RW disc contains time-code information called ATIP.

ATIP is abbreviation of "Absolute Time In Pre-groove" in the wobbling groove by modulating the carrier frequency.

(Address information is pre-formatted to ATIP on the CD-R / CD-RW disc and method for the guide groove to wobble by FM modulation.)

Figure 6 shows the composition of ATIP.
