/**
* call-seq:
* put(first_track, sectors, offsets)

*
* Use this instead of read if the TOC information was already read elsewhere

* Throws an _Exception_ if the CD's TOC can not be read.
*
* <b>Parameters:</b>
* [first_track] The number of the first track on the disc (usually 1).
* [sectors] The total number of sectors on the disc.
* [offsets] Array of all track offsets. The number of tracks must not exceed 99.
