Methods for efficient host processing of data files selected for recording to an optical disc media

Abstract

Methods for the processing of data files to be recorded on an optical disc are provided. A selection of data to be recorded to the optical media is received and a record data structure for each file in the selection of data is created. A set of pointers is generated to sequence each record data structure in a writing order, defining a dynamically sequenced list of record data structures. Each of the record data structures is processed to produce an ordering data structure corresponding to each file in the selection of data. The ordering data structure corresponding to each file in the selection of data is processed to write the selection of data onto the optical media in the writing order.
