Q: Why its so hard for some drives to read/write 99min CDs?

A: CD-R media that recorded over 95min cannot be read from all CD-RW drives. These kind of media has two address:

a) At the inside - theoretical- (ATIP) area
b) Outside -real address-

CD-RW drives cannot judje which address to read (inside or outside)..

Other drives(Audio CD Player/CD-ROM Drive) can not read the theoretical address inside. Therefore,can read 99min recorded CD-R.

This isn't true.

The ATIP of any disc has a max of 80 min, so according to your theory, any CD longer than 80 min is just as hard to read and write as a 99 min cd. The ATIP is only avaliable with a special MMC read command, which wouldn't be used in typical reading anyway.

As for the sector addressing, it allows up to 99 min, so there's no problem there.

Actually the problem with 99min media is higher with some CD-RW drives and with some (older) readers. For example all Sanyo based drives can record and read up to 93mins, while Plextor drives up to 95mins.

As i said, most CD-ROM/DVD-ROM cannot read ATIP information so they have higher compatibility with 90+ mins media.

Most of the 90min media doesn't include two addresses so no problem there.

And it doesn't make it any more true.

90 min media (or all media, for that matter) don't have any addresses on them until they are burned.

It all still means nothing to me and possibly hundreds more of your subscribers, such as addresses whether they be inside or outside

This is nonsense, forget it.


What (I think) he's talking about is that the ATIP max is limited to 80 min. However, ATIP is not required for reading, even a CD-R drive will not check it for a simple READ_CD command. In theory, any drive which can read an overburned disc (no matter how little overburned) can read a 99 min disc, but in practice, most drives cannot read such tightly spun discs (even though they are technically allowed).

Some CD-RW drives (like Sanyo) have limited their overburning/reading capabilities up to 93mins cause of our explanation, at least according to their information

HI guys. Im so lost when it comes to CD media but... I bought 900 megs CDr discs and now I wonder if my Memorex CD-RW recorder model 1040 (24x10x42) can write on them. Please don't start to talk about ATIP (I also got a DVD rom to read discs but that is NOT an recorder)

SO what I get out of there post is that I can read a 99 min Cd.
But can my memorex burn 99min /900 megs info?

If you download Nero CD Speed, it has the ability to do an overburn test. You can test your drive to see if it will overburn.

The discs will still work for you. If your burner is not able to burn out that far they will just burn to what the writer is capable of doing. So go ahead and open one and do an overburn test.
