[comp.sys.mac.programmer] CD-Rom data structures?

Hi,

	Are there any good sources to look at for trying to figure out a cd-rom data
	structure? Are there any tech notes for cd-rom data structures? Any help
	appreciated.

There are several possible formats for CD-ROM discs on the Mac:

1) Native HFS.  This is documented in the File Manager chapters of Inside 
Macintosh.

2) ISO 9660.  The "official" standard is ISO 9660, "Information processing 
--Volume and file structure of CD-ROM for information interchange." You 
can get it from Global Engineering Documents, 800-854-7175, or 
714-261-1455.  The document is very pricey: $60 for 31 pages. Its also 
about as easy to understand as the tax code. 

3) High Sierra.  This is the older, pre-official format that eventually 
became ISO 9660 after modifications.  The High Sierra standard is 
available from:
National Institute of Standards & Technology
Administration 101
Library E-106
Gaithersburg, MD 20899
(301) 975-2814

Does that answer the original question?  The term "data structures" & 
CD-ROM is rather vague...
