Toast does see the 800 MB disks as having only 90 MB. It would be out of character for Toast to burn to discs that are not universally readable. This makes sense to me because Toast emphasizes compatibility with multiple drives and systems. That's what I've read but have no way of confirming. Toast considers anything more than that as being overburning which it does not support. If you use larger-capacity CDs Toast still only burns the maximum that fits standard CDs. I've read posts here in the past that Toast does not support burning more than 700 MB to CD-R media. Red Book (audio CD standard) Capacity up to 700 MB. Also, due to the limitations of the data structures in the ATIP (see below), 90 and 99 minute blanks will identify as 80 minute ones and have to be burned using the 'overburn' options in the CD recording software. Some drives use special techniques to write more data onto a given disc, such as Plextor's GigaRec allowing as much as 1.2 GiB onto a 99 minute disc. There are also 90 minute/790 MiB and 99 minute/870 MiB discs, although they are rare. Most CD-Rs on the market have an 80 minute capacity. CD-R/RWs are also available with capacities of 79 minutes, 59 seconds and 74 frames (marketed as 80 minutes) /736,966,656 bytes (702 MiB), which they achieve by burning at the maximum allowable tolerances specified in the Orange Book CD-R/CD-RW standards. It has a storage capacity of 74 minutes of audio or 650 MiB of data. I have also searched Wikipedia (for the records):Ī standard CD-R is a 1.2 mm thick disc made of polycarbonate with a 120 mm or 80 mm diameter. Just be careful using a disc like this overburned, especially for important data. With data, if a drive burns 800MB or more, but another drive can only read 750MB, it because a problem when you want your data back. The main problem results with trying to read back the data, especially if you are burning an Audio CD. Most drives, even with over burn can't burn a full disc. The standard supports both 650 and 700MB CD-R and I believe that 700MB is more common any more.Ĩ00 and even 900MB CD have been made, but they have never became part of the official spec. CD-RW continue to be 650MB, however, CD-R were increased to 700MB.
