Definitions for "Track-at-Once"
Keywords:  gap, laser, write, disc, toc
A single-session method of writing one or more tracks to a recordable disc in which the table of contents and Lead-In area are added after the Program Area is completed. The disc is fixed after the TOC and Lead-In are appended and no further tracks can be added. Discs created in this manner are not suitable for masters to use in mass replication. Compare to Disc-at- Once.
The track-at-once mode records each track of a CD individually.
Mode of writing that allows a session to be written in a number of discrete write events called tracks. The mode mandates a minimum track length of 300 blocks (4 seconds), which equates to around 700KB, and a maximum of 99 tracks per disc. The disc may be removed from the writer and read in another writer before the session is closed (‘fixated’).
