In YELLOW BOOK, the pre-gap is divided into two parts. The first part (more than 1 second) is encoded as MODE1 according to the definition of the previous track, and the second part (more than 2 seconds) is encoded as MODE2. It is stipulated that
In this script, the PostGap command is interpreted as the "first part of the pre-gap" and the PreGap command is interpreted as the "second part of the pre-gap."
