Basically you just read the sectors that contain the information and then
use what is there, according the format you mentioned.

Word of caution, don't write to said sectors.  Why?  When the diskette is
read, DOS reads in the directory information.  When you change any of the 
sectors, DOS won't know about them, as the copy in memory isn't changed.

When I use Norton's Utilities to play with hard disk directories, I make
the DOS read a different sub-directory and then read the one I changed,
so DOS will know about the changes.
