Hello,
Thank you for your response.
ISO 9600 refers to as CDFS (Compact Disc File System).
It defines a minimal set of common file attributes (directory or ordinary file and time of recording) and name attributes (name, extension, and version), and used a separate system use area where future optional extensions for each file may be specified.
Universal Disk Format (UDF) is a profile of the specification known as ISO/IEC 13346 and ECMA-167[2] and is an open vendor-neutral file system for computer data storage for a broad range of media. In practice, it has been most widely used for DVDs and newer
optical disc formats, supplanting ISO 9660
Mode 1 is for data, mp3 because it incorporates good error correction coding.
Mode 2 is only for vcd/svcd movie cd's.
Note: Mode 2-1 for data and Mode 2-xa for vcd/svcd.
Disk at once mode of recording directly burns all tracks without the laser taking any break in between. Hence this recording mode can use the full storage capacity of the disk. When creating a master disk for duplication, this is the recording mode used. This
mode should be used when finalizing a disk in one writing session.
Using multiple sessions means that information can be written to the first part of the disk, and then later more information can be appended to it in the unused space left after the first session.
I hope this information helps.
Thank you
