>> if I remember right there's a recommendation in the yellow book saying there shall be only one mode 1 track on a CD. >>So if drives do not read mode 1 multisession disks they are completely according to the standard following even all the recommendations. As I said, there are many ways to implement the reading of a standard. Some drives add features, some leave some of them out. CD+G is an example – it's defined in the Red Book, but only a few players ever included it. Red Book defines reading speed as 75 sectors per second, this was carried through to Yellow Book. Some drives read faster than that. >>And the Philips Sony white paper 'An introduction to CD-I Bridge Disc' which described for the first time the basic concept of the ISO 9660 extensions for MultiSession speak of mode 2 disks only. CD-I is Mode 2. Bridge Disc is based on Orange Book and Green Book. The Orange Book, Part 2, which refers to the Yellow Book for digital data structure, is really rather vague as to which Mode to use for multisession; it specifically excludes or recommends neither. The commonly accepted interpretation is that either is allowed, as long as all sessions are one or the other. The only reference to reading the data back that I can find is in the first paragraph: "the recorded CD-WO disc is 'Red Book compatible' so it can be played back on conventional CD players."
