absolute time in pregroove (CD) (ATIP)

The grooves of CD-RW recordable media are prepared with a pregroove.

In this pregroove, the exact timing information is already burned in as Absolute Time in Pregroove (ATIP) for the various areas. This includes the length of the spiral track, the start of the lead-in and lead-out, the lowest and highest recording speed, the power ratio between erase and write, and several other values. Via the ATIP code, the CD drive can determine the position of the read head and thus the rotation speed.
