 @subsection Mode2
 Mode 2 data CDs are the same as mode 1 CDs except that the error
-detecting and correcting codes are omitted. This is similar to audio
-CDs, i.e. the mode 2 format provides a more flexible vehicle for
-storing types of data that do not require high data integrity: for
-example, graphics and video can use this format. But in contrast to
-the Red book standard, different modes can be mixed together; this is
-the basis for the extensions to the original data CD standards known
-as CD-ROM Extended Architecture, or CD-ROM XA.  CD-ROM XA formats
-currently in use are CD-I Bridge formats, Photo CD and Video CD plus
