Noun
ATIP (uncountable)
Initialism of absolute time in pregroove (“a CD-R technology by which the 'wobble' of the groove is modulated to carry a signal”).
As well as providing timing information, the ATIP (absolute time in pregroove) is also a data track containing information about the CD-R manufacturer, the dye used and media information (disc length and so on). Source: Internet
Also, due to the limitations of the data structures in the ATIP (see below), 90 and 99 minute blanks will identify as 80 minute ones. Source: Internet
