Abstract
Disclosed is a method for handling buffer under-runs during disc recording sessions on an optical disc. The method includes the operations of recording a volume descriptor sequence for the recording session, and then recording the data for the recording session following the volume descriptor sequence. A track of the recording session is closed upon an occurrence of a buffer under-run, and a continuation of the data is recorded in a next track of the recording session. A file system is then written following the data written in the next track, such that the volume descriptor sequence has a pointer to the file system. In one example, the method includes estimating a number of buffer under-runs before beginning the recording, and adding a correction increment corresponding to the estimated number of buffer under-runs that is configured to define a location for writing the file system.
